Jack Dorsey and Marc Andreessen are still beefing over crypto

The a16z co-founder is putting the “block” in “blockchain.”

Marc Andreessen kicked off the new year by resuming what has become one of the quirkiest tech feuds in recent memory.

“In 2022, I am GOING TO BLOCK SO MANY PEOPLE,” he declared in a Jan. 1 tweet featuring a meme of J-Lo and Ben Affleck.

It was hard not to take it as a gleeful dig at Jack Dorsey, who shared that Andreessen had blocked him on Twitter in late December. The CEO of Block (this is already awkward) had set off the tit-for-tat that month by bashing VCs and Web3 in general — a stance that apparently prompted the co-founder of Andreessen Horowitz, which runs one of the biggest crypto funds in the world, to block Dorsey on the social network he created.

This wasn’t just an ordinary dispute between two high-profile tech figures. Andreessen helped popularize the web browser, which makes him a key figure in Web 1.0. Dorsey, in turn, helped create what’s now known as Web 2.0 with Twitter. And now their battle has turned the spotlight on the raging debate over Web3, the next iteration of the internet revolution based on blockchain technologies.

It was easy to assume Dorsey, who’s been vocal about his embrace of bitcoin, was in on the Web3 movement. Crypto’s explosive growth helped turbocharge Square — so much so that Dorsey renamed it Block, launched a number of crypto initiatives like a hardware wallet and stepped down as Twitter boss to go all-in on crypto.

But Block had its doubters, with some crypto advocates characterizing it as a Web 2.0 company trying to how-do-you-do-fellow-kids its way into Web3.

Finally, Dorsey had enough.

On Dec. 20, he fired back at the “haters” with a tweet: “You don’t own ‘web3.’ The VCs and their LPs do. It will never escape their incentives. It’s ultimately a centralized entity with a different label.”

It was an odd flareup from a tech entrepreneur who launched two iconic tech brands with help from the VC world. Dorsey didn’t mention Andreessen, whose firm was so eager to invest in Twitter that it bought shares on the secondary market and who at one point expressed his regret in not investing in Square.

Andreessen, now considered one of the most successful investors in tech, was quick to express his disapproval with a Twitter block, a move he’s become infamous for. Dorsey promptly tweeted a screenshot of the ban notice with a quip: “I’m officially banned from web3.”

Dorsey’s quip, or the online response to it from his followers, appeared to trigger a series of funny and sometimes nasty tweets from Andreessen, including a “call for startup pitches” for a "block button, but for real life."

Meanwhile, Dorsey took fire from other corners of the crypto realm, including a Montreal-based investor who told him if he looks "outside of your bubble of rich dudes you’ll see that there are creators actually building web3 and a whole revolution in the form of digital renaissance.”

Dorsey hit back: “I care only about decentralized, secure, private foundations without single points of failure. And I’m focused on that.”

He tried to explain the stance of bashing VCs even though he received money from some of them: “I’ve learned from the issues taking on VCs creates. Block *had* help from VCs yes. But ones that know their place.”

Dorsey seemed to have grown tired of the debate by New Year’s Day. His handful of tweets since then included a retweet of a birthday greeting to bitcoin, which marked the 13th anniversary of its creation Monday.

But as 2022 rolled in, Andreessen clearly wasn’t ready to let go. He followed up his New Year’s Day tweet with a series of memes featuring a train slamming into a school bus labeled “Bad Followers.” Another featured an arrow fired into the eyes of a knight with the caption: “Blocked!”

The Twitter meme rant led one of his followers to quip: “I'm sure either Marc is high or his account [was] hacked or maybe he's just turned into [us teens].”


A pro-China disinformation campaign is targeting rare earth miners

It’s uncommon for cyber criminals to target private industry. But a new operation has cast doubt on miners looking to gain a foothold in the West in an apparent attempt to protect China’s upper hand in a market that has become increasingly vital.

It is very uncommon for coordinated disinformation operations to target private industry, rather than governments or civil society, a cybersecurity expert says.

Just when we thought the renewable energy supply chains couldn’t get more fraught, a sophisticated disinformation campaign has taken to social media to further complicate things.

Known as Dragonbridge, the campaign has existed for at least three years, but in the last few months it has shifted its focus to target several mining companies “with negative messaging in response to potential or planned rare earths production activities.” It was initially uncovered by cybersecurity firm Mandiant and peddles narratives in the Chinese interest via its network of thousands of fake social media accounts.

Some of the most astounding tech-enabled advances of the next decade, from cutting-edge medical research to urban traffic control and factory floor optimization, will be enabled by a device often smaller than a thumbnail: the memory chip.

While vast amounts of data are created, stored and processed every moment — by some estimates, 2.5 quintillion bytes daily — the insights in that code are unlocked by the memory chips that hold it and transfer it. “Memory will propel the next 10 years into the most transformative years in human history,” said Sanjay Mehrotra, president and CEO of Micron Technology.

Ripple’s CEO threatens to leave the US if it loses SEC case

CEO Brad Garlinghouse said a few countries have reached out to Ripple about relocating.

"There's no doubt that if the SEC doesn't win their case against us that that is good for crypto in the United States,” Brad Garlinghouse told Protocol.

Ripple CEO Brad Garlinghouse said the crypto company will move to another country if it loses in its legal battle with the SEC.

Garlinghouse said he’s confident that Ripple will prevail against the federal regulator, which accused the company of failing to register roughly $1.4 billion in XRP tokens as securities.

The Supreme Court’s EPA ruling is bad news for tech regulation, too

The justices just gave themselves a lot of discretion to smack down agency rules.

The ruling could also endanger work on competition issues by the FTC and net neutrality by the FCC.

The Supreme Court’s decision last week gutting the Environmental Protection Agency’s ability to regulate greenhouse gas emissions didn’t just signal the conservative justices’ dislike of the Clean Air Act at a moment of climate crisis. It also served as a warning for anyone that would like to see more regulation of Big Tech.

At the heart of Chief Justice John Roberts’ decision in West Virginia v. EPA was a codification of the “major questions doctrine,” which, he wrote, requires “clear congressional authorization” when agencies want to regulate on areas of great “economic and political significance.”

Microsoft and Google are still using emotion AI, but with limits

Microsoft said accessibility goals overrode problems with emotion recognition and Google offers off-the-shelf emotion recognition technology amid growing concern over the controversial AI.

Emotion recognition is a well-established field of computer vision research; however, AI-based technologies used in an attempt to assess people’s emotional states have moved beyond the research phase.

Microsoft said last month it would no longer provide general use of an AI-based cloud software feature used to infer people’s emotions. However, despite its own admission that emotion recognition technology creates “risks,” it turns out the company will retain its emotion recognition capability in an app used by people with vision loss.

In fact, amid growing concerns over development and use of controversial emotion recognition in everyday software, both Microsoft and Google continue to incorporate the AI-based features in their products.

“The Seeing AI person channel enables you to recognize people and to get a description of them, including an estimate of their age and also their emotion,” said Saqib Shaikh, a software engineering manager and project lead for Seeing AI at Microsoft who helped build the app, in a tutorial about the product in a 2017 Microsoft video.
