Crypto-focused US bank Silvergate in crisis

The big fear of any bank is that people lose trust in its ability to pay out money.

This is what currently happens with Silvergate. The US bank had served many crypto clients, making it simpler to convert dollars to Bitcoin, etc. The bank achieved a profit of $76m in 2021, and it experienced a net loss of $949m in 2022.

By March 1 this year, the bank said it would not file its annual report to the SEC on time and that the losses were even higher than previously known. In the past few days, crypto exchanges like Coinbase and others said they would stop transactions with the bank. The bank has warned that it might not survive the next 12 months.


Crypto exchange Binance must answer difficult questions

Another crypto company under some external pressure is Binance. The crypto exchange seemed to emerge as the winner after the collapse of FTX. But now Forbes Magazin has published an investigation. The journalists say they found evidence that Binance invested $1.8B, which was meant as collateral for customers’ stablecoins, into a hedge fund. Such practice is considered risky and problematic because there is no real transparency. Binance says nothing is wrong; all transactions were within the boundaries of proper investment. But the market is watching.

Why do the EU and US want to ban TikTok?

TikTok is considered suspicious. Governments outside of China worry that the app could be used to track users and get their data, such as names, locations and other information. It could be that Bytedance has to comply with requests by the Chinese government. As a result, several governments have ordered their staff to delete TikTok from their phones. This week, the EU, the US, Canada, and Denmark are considering a ban.

Benedict Evans, an expert in the digital economy, says the threat is not that people could be spied upon and their data being passed on, as operating systems by now provide considerable protection. Amazingly, in a world of digital devices and highly measurable data flows, the recent actions are primarily based on assumptions but no more profound knowledge of actual data misuse.



How EU data acts affect the handling of data

This spring, several EU acts will be put into practice. Currently they still in draft status. But companies and organizations should anticipate that the new rules go further than GDPR. On the upside the rules are not meant to be only restrictive. In fact the EU commission hopes that the new guidelines will enable a market for data and a productive exchange of information between companies.

Here is a quick overview of the several acts from an article published by Mckinsey:

  • The Data Governance Act creates a new way of managing data to increase trust in and facilitate data sharing.*
  • The Digital Markets Act creates fair and contestable markets for innovation, growth, and competitiveness in the digital sector.
  • The Digital Services Act creates a safer digital space where the rights of all users of digital services are protected.
  • The Data Act regulates access to data in B2B, B2C, and B2G (business-to-government) relationships and while switching between cloud providers.
  • The AI Act enacts stringent regulations of (high-risk) AI systems and prohibiting certain practices.

Reuters investigation reveals a recycling initiative by Dow as just greenwashing

Determining whether certain initiatives actually deliver on their promises is often difficult in today’s information environment. A few weeks ago, The Guardian had a story that up to 90% of rainforest carbon offsets are worthless.

This week Reuters published the results of an investigation into a sneaker recycling program initiated by the government of Singapore and Dow, the US petrochemical company. They equipped used sneakers supposed to go into the program with hidden AirTags to see where they would end up. As you might have suspected: They were not recycled. Instead, the investigators found them in second-hand stores in Indonesia. Just one story reveals a massive gap between promises and reality. But the story is an example of what needs to change to achieve trustability in many areas of environmental activity.



The new hot job: AI whisperer

The ability to write the right “prompts” for the new AI platforms is becoming a profession in high demand. It is not coding, not writing. Instead, generating prompts is finding the fitting instructions for the best possible results from an AI platform. There are pretty several articles and YouTube videos about the art of the prompt. One awe-inspiring video (link below) shows how to generate highly realistic pictures using certain variations of prompts. You can even use ChatGPT to help you write prompts for visual AI platforms like Dall-E or Midjourney. There are evolving dark arts here, too. An example is the “prompt injection”, – which aims to instruct an AI platform to reveal its instructions (see link below to Ars Technica).

AI companies rush to find income streams

Operating the newest AI platforms is expensive, and they demand a lot of computer processing, translating to high hardware, software and electricity costs. Chat GPT reached 100 million users in record time. As a result, AI companies are quick to introduce usage options for money.

Last week Open AI released an API which enables the use of Chat GPT for business. The costs are “0.002 per token or about 750 words”. According to Techcrunch, Snap, Quizlet, Instacart and Shopify are early clients.

One company already seeing increased sales is Nvidia. The graphic card specialist produces a $10,000 chip called the A100, which is in strong demand because of its performance. Need for the follow-up model, the H100, which is only recently going into mass production, grows as fast. (CNBC)

For illustration

The latest version of Stable Diffusion, an image generator, was trained on 256 A100 GPUs, or 32 machines with 8 A100s each, according to information online posted by Stability AI, totaling 200,000 compute hours.

At the market price, training the model alone cost $600,000, Stability AI CEO Mostaque said on Twitter, suggesting in a tweet exchange the price was unusually inexpensive compared to rivals. That doesn’t count the cost of “inference,” or deploying the model.

CNET Editor leaves the job to work on AI content

CNET recently admitted that they used Chat GPT for several published stories, and the criticism was that the origin of the stories was not revealed. Now the CNET editor-in-chief has resigned and will join Red Ventures, a VC fund which had bought CNET, to work on AI projects. At CNET, management announced mass layoffs.

Visual misinformation on Facebook

Scientific results of an extensive study of visual misinformation on Facebook:

“We conduct the first large-scale study of image-based political misinformation on Facebook. We collect 13,723,654 posts from 14,532 pages and 11,454 public groups from August through October 2020, posts that together account for nearly all engagement of U.S. public political content on Facebook. We use perceptual hashing to identify duplicate images and computer vision to identify political figures. Twenty-three percent of sampled political images (N = 1,000) contained misinformation, as did 20% of sampled images (N = 1,000) containing political figures. We find enormous partisan asymmetry in misinformation posts, with right-leaning images 5–8 times more likely to be misleading, but little evidence that misleading images generate higher engagement.”

Transparency by design: How next-gen blockchain could help to make greenwashing impossible

Reliability of information and data is the big goal for the future. Blockdata reports a company from Vienna, Austria, named Riddle&Code that tackles this problem. The team has previously worked for several industrial clients, including BMW and Wien Energy, a regional energy provider.

“The company is is now evolving from a project-driven company to a product company. In doing so, it’s taking the well-worn path taken by Amazon with AWS, in the sense that it is making its own infrastructure available commercially, so that others can benefit from the software and hardware stack they’ve developed in-house.”

“Everybody says, ‘We don’t want to talk with the banks, we don’t want to know what they’re doing, etc.’ But they’ve actually been around for 300 or 400 years. They have a lot of experience on how to do things actually, or how not to do things.”

Top search results could lead to online scammers; FBI recommends ad blockers when using search

Cory Doctorow, a well-known journalist, author and activist, recently published a screenshot of a search via Twitter where the top search result for a restaurant led to a fake website designed to scam users. The actual restaurant was also showing up in the search but ranked lower.

This new approach by scams is hard to detect by Google. As one result, the FBI recommends using an ad blocker to shelter against such falsified and malicious links.

“…cyber criminals are using search engine advertisement services to impersonate brands and direct users to malicious sites that host ransomware and steal login credentials and other financial information.”

AI-generated voice used to break into a bank account

Many banks offer the option to enter an account using a voice command. A reporter for VICE managed to trick a bank system using a free choice to cheat the system. Experts suggest that banks re-consider and switch to different methods of identity verification.


Signal warns it might stop services for the UK should “Online Safety Bil” undermine message encrypt.ion

The Online Safety Bill is currently passing through the UK parliament. Boris Johnson, the former prime minister, introduced it. The government and child protection have argued that encrypted messages make it difficult to fight child abuse.

The UK Home Office said in a statement: “It is important that technology companies make every effort to ensure that their platforms do not become a breeding ground for paedophiles. The Online Safety Bill does not represent a ban on end-to-end encryption but makes clear that technological changes should not be implemented in a way that diminishes public safety – especially the safety of children online”.

Meredith Whittaker, president of Signal, told the BBC it was “magical thinking” if government agencies in the UK want to provide privacy, but “only for the good guys. Encryption is either protecting everyone or it is broken for every. one.”

Apple had previously suggested a system where content where photos on phones or tablets could scan for child abuse but had abandoned the plans after much criticism.


Mozilla study: Developer privacy claims on Google Play can not be trusted

A study by Mozilla calls the labels used in the Google Play Store “a joke” and “useless”:

“The study looked at the privacy information that app developers are supposed to fill out in the Google’s Play Store and compared those details to the apps’ privacy policies. The privacy labels are supposed to give you information about an app’s data practices so you can make informed choices, but the study found the labels are close to useless. Just six apps of the 40 apps in the study got a passing grade.”



Using new AI platforms, the next generation of “deepfakes” could leada  to a whole new level of damage

The people in the videos look r, and they speak compellingly. But they are not real, and their words might be a believable lie. This is the scenario experts say could be the next level of “deepfakes”.

The combination of several AI platforms “…can also be used to more quickly and cheaply build an army of people who don’t exist, fake actors capable of fluently delivering messages in multiple languages. That makes them useful, says Gregory, for the “firehose” strategy of disinformation preferred by Russia, along with everything from “deceptive commercial personalization to the ‘lolz’ strategies of shitposting at scale.”

It is tempting to use generative AI for legal documents. What could go wrong?

Without the help of technology, lawyers spent hours over hours in legal research and the gradual writing of contracts and other legal documents. Now, generative AI has arrived. And it is quite tempting to use the technology to generate legal texts. On one side, experts consider legal documents to be a good use case for generative AI.

There is already a dedicated an AI platform for this use case called Harvey. Law experts created the company behind Harvey using ChatGPT and received $5 million in funding from OpenAI in November 2022 (TechCrunch). The platform describes itself as a “copilot for lawyers”.

Wired has a story with statements from several prominent law firms. Most are optimistic about the use cases for generative AI, for example, for standard documents or early-stage research. But at the same time, there are worries about current platforms making things up and tending to “hallucinate” about topics poorly defined in the learning material. The significant risk is that some law providers signed not to be more cautious and deploy AI to mass-produce certain legal documents – only to find out later that it was a big mistake.

European Union starts consultation on whether some companies should pay more for using internet traffic

The EU considers demanding a contribution from the largest tech companies. The money would then be deployed for upgrades for phone lines both at home and mobile. Currently, a document aims to collect opinions in a survey as public consultation. The EU internal market commissioner, Thierry Breton, will discuss the plans at Barcelona’s Mobile World Congress (MWC). The critical argument that big traffic generators should pay more has been part of lobbying by larger telecommunication companies for some years. Now the EU seems to agree with this view. Opponents are highly critical of such different pricing. They say that the move might open a box of pandora because telcos will be free to draw the line for heavy traffic and enable them to charge all kinds of companies.

Open AI aims to avoid biased ChatGPT output

“How should AI systems behave, and who should decide?” That is a relevant question. But it gets even more relevant if this is the headline on a blog post on the website of a currently leading AI company. OpenAI is determined to avoid the big (and costly) controversies that have riddled other large content platforms, such as YouTube, Twitter, and Facebook, for years. Yet, with the incredible dynamics unleashed as AI chat software is added to the search, avoiding big problems is the big challenge.

Researchers warn about the potential of AI use for “automated propaganda”

There is a horror scenario the newest AI content platforms could help to produce “automated to spread very convincing and effective disinformation”. Only last week, there were news reports in Canada that state-funded actors fueled the”Freedom Convoy” in 2022 to weaken the Trudeau government.

Now researchers from leading AI companies warn that without preparation, such events might become more regular:

“A cohort of researchers from OpenAI, Stanford, and Georgetown Universities are warning that large language models like the kind used by ChatGPT could be used as part of disinformation campaigns to help more easily spread propaganda.”

Google launches “privacy sandbox” on Android as an alternative to user tracking for ads

The question here is not so much whether it works but what happens if this approach by Google fails. The company would be in even bigger trouble than through the recent competition from Microsoft/Open AI.

From The Verge:

“Around this time last year, Google revealed it was working on a multiyear initiative to improve privacy and remodel ad tracking on Android phones, bringing the mobile platform in line with Apple’s App Tracking Transparency feature for iOS. Following the release of an early developer preview last April, Google says the first beta for Privacy Sandbox on Android will start rolling out tomorrow (ed. = February 15 2023) to a limited number of Android 13 devices, allowing users and developers to test the new technology in the real world.” (The Verge)

From Ars Technica:

“Privacy Sandbox, on Chrome and Android, tracks users by interest groups rather than individually, which Google claims is a privacy improvement. Android will soon build an advertising profile of you, and the user interface will let you block “interests” you don’t want to see ads for.” (Ars Technica)

CEO Susan Wojcicki steps down as CEO of YouTube

Is it relevant when a senior tech executive steps down from leading a large platform? Yes, in this case, it is notable. First, this is a reminder that for the past 25 years, intelligent people working for Google have built the dominant platforms in several areas. Google is the leader in search, and YouTube is the biggest video platform.

“During her tenure, YouTube became increasingly important to the business for Google, which bought the site in 2006, and Alphabet, the holding company that houses both of them: In 2022, YouTube generated $29.2 billion in ad sales — more than 10 percent of Alphabet’s total revenue.”

Launch of Bard is considered “un-googly.”

“Google employees aren’t holding back about the substandard launch of ChatGPT competitor Bard. According to CNBC, which viewed the posts, staffers have been posting memes on Google’s internal forum Memegen about how the launch of the generative AI tool was handled, directly calling out CEO Sundar Pichai for the misstep. Memes which got a lot of upvotes included a picture of Pichai and said “Dear Sundar, the Bard launch and the layoffs were rushed, botched, and myopic.”



Mastodon usage going down after the spike

The takeover of Twitter by Elon Musk in October 2022 led to an exodus of users; many selected Mastodon as an alternative. But Mastodon can not compete with Twitter, at least for now – there are not as many users, so the network effect of more prominent Twitter is hard to beat.

“Mastodon’s active monthly user count dropped to 1.4 million by late January. It now has nearly half a million fewer total registered users than at the start of the year. Many newcomers have complained that Mastodon is hard to use. Some have returned to the devilish bird they knew: Twitter.”

Analysis: 24% of tokens launched in 2022 lost up to 90% of their value, indicating “pump-and-dump” activities

“Pump and dump schemes in traditional finance are quite simple: Holders of a tradable asset, such as stock in a company, will heavily hype and promote the asset to other investors, often using misleading statements, causing the price to rise rapidly as new investors buy. The holders will then sell their overvalued shares at a profit, causing the price to plummet, leaving the newer investors stuck with a low-value asset. Unfortunately, pump and dump schemes have also become common in the crypto world.”

Hope for the next-gen internet, with new risks and dangers

How AI is integrated into search and other online services is a big question for the coming years. Precisely, what concepts will be followed?

The outcome could be positive: Better search results and better information. Many knowledge jobs could become more productive because the struggle of searching for information could go away. The internet could become a productivity machine, helping us find answers to complex problems.
But there are considerable risks, too. It starts at the foundation: Which material was used for training the new generation of AI platforms? Which pictures, words, insights, concepts, codes and numbers? Who owned those before? How are these info bits used now in AI?

From “The Conversation”:

“ChatGPT is underpinned by a large language model that requires massive amounts of data to function and improve. The more data the model is trained on, the better it gets at detecting patterns, anticipating what will come next and generating plausible text.

OpenAI, the company behind ChatGPT, fed the tool some 300 billion words systematically scraped from the internet: books, articles, websites and posts – including personal information obtained without consent.

If you’ve ever written a blog post or product review, or commented on an article online, there’s a good chance this information was consumed by ChatGPT.”

Macro raises $9.3m for intelligence on top of digital documents

Could standard documents like PDFs become more usable? A company called Macro just got funding for their ideas to do just that.

“Jacob Beckerman, a former investment logic engineer at Bridgewater Associates, grew frustrated using standard document apps like Acrobat and Microsoft Office to print out and mark up documents. He wondered why there wasn’t a way to read and write on a PC that felt as fluid as paper, which led him to experiment with PDF processing software.

By 2020, those experiments had grown into a fully fledged, custom PDF editor that Beckerman helped to build from scratch. Using AI, the editor — called Macro — pulls out key terms, sections and equations to make documents interactive and hyperlinked.”



Bank of England published papers on the digital pound

The Bank of England has published two papers discussing a digital pound’s benefits and potential set-up. The current approach favours a central database and does not use smart contracts or blockchain.

In a separate technical paper, blockchain technologies were described that “might have advantages in guaranteeing consistency and resilience”, combined with “privacy, scalability and security challenges. Centrally governed, distributed database technologies might achieve the ledger requirements without limitations. Therefore, these technologies might be appropriate for the core ledger design.”

Advice on how to report about AI for journalists

Two scientists have prepared an overview where journalists (and everyone else) should be careful with claims and speculation about what the new generation of generative AI might evolve to.

“We noticed that many articles tend to mislead in similar ways, so we analyzed over 50 articles about AI from major publications, from which we compiled 18 recurring pitfalls. We hope that being familiar with these will help you detect hype whenever you see it. We also hope this compilation of pitfalls will help journalists avoid them.”

Google rushes to counter ChatGPT

Google is preparing its own generative AI services. The company had an all-hands meeting where employees were concerned about the sudden popularity of OpenAI, which Microsoft backs. The head of AI at Google argued that there is currently a “reputational risk” when providing false information.

One tool currently being tested is a chatbot called “Apprentice Bard”, based on LaMBA (Language Model for Dialogue Applications). Google has developed this model.


In addition, Google invested $300 million in an AI start-up called Antrophic. The company has developed a chatbot called “Claude”.

Rest of World has an interview with the company’s CEO, who plans to restart the app. The article provides a glimpse into non-EU and non-US markets and how trust, content & payment elements are handled elsewhere. The patterns are similar, but the stories are always different.

New York Times article: “My Watch thinks I’m dead”

Apple watches have a feature to automatically alarm rescuers in case of an accident. What could go wrong? Well, the Apple watches seem not to be calibrated well enough. The current generation can not distinguish between a “bump” from an accident or a jump while skiing down a slope. As a result, rescue services are getting several emergency calls and finding the watch owners without any issues.

Netflix has started rolling out new rules to prevent password sharing outside of the household

Netflix wants to reduce the number of people watching through password sharing. In the future, devices will have to log in to a local Wifi associated with an account at least once per month. Rules are not final but already draw considerable criticism – e.g. from families with two locations, e.g. after a divorce.



Kids are hooked to YouTube everywhere

If you have kids, you will be familiar with a constant debate about screen time on mobile phones, iPad or TVs. Studies now show that kids’ channels are the highest earners for YouTube.

“Data suggest that many children are watching a lot more than that, however: up to six hours per day for American children aged 8-12, and more for teenagers. The most popular global YouTube sites, meanwhile, like CoComelon and others that feature nursery rhymes, songs, animals, and babies, are aimed at very young children.”

The data:

“Content for children tops the YouTube earnings charts in North America, most of South America, Russia, Sweden, Germany, Portugal, and much of Central and Eastern Europe, Jordan, Israel, India, Indonesia, Thailand, Mongolia, Australia, Turkey, and Kazakhstan. Only in much of Africa do kids’ shows not figure as the most lucrative channels on YouTube. Globally, children’s channels are more popular than gaming channels or those devoted to How-To videos, general entertainment, comedy, or animals, some of the other most popular types of content.”

A big question is: What amount of screen time is healthy for kids 8-12 and younger? Data from the US suggests that kids watch up to six hours daily.


Damus, a fast-growing Twitter alternative, has been pulled from Apple App Store in China after two days

Enterprise blockchain use cases gaining adoption

This links to an excellent white paper/analysis of the gradual evolution of blockchain technology towards wider adoption among governments and enterprises. Notably, in almost all use cases without digital currencies.

“Governments, business entities, and organizations have been pursuing blockchain technology to meet their unique needs, which seldom involve digital currencies. Blockchain technology is secure, traceable, immutable, and transparent across distributed networks. These traits make it a good fit for use cases that are hard to underpin using traditional infrastructure.”


After the loss of reputation and trust, what’s next for crypto?

A good quote to separate two areas of blockchain application:

“One key lesson of 2022 is that “money crypto” and “tech crypto” need to be treated differently. Money crypto in this context includes crypto-financial services such as custody, exchanges, market making, investing and lending. And tech crypto includes open-source, public permissionless innovation such as blockchains, decentralized finance (DeFi), non-fungible tokens (NFT), Web3 gaming, wallets, tools and infrastructure. Financial stability and consumer protection failures in crypto did not arise from the failure of technology, but the failure of oversight and controls.”
