Figma co-founder and CEO Dylan Field said Thursday that artificial intelligence doesn't pose a serious threat to the future of the design software company, which is on the verge of debuting on the public markets. "We're in this moment where you might, if you're singularity-pilled, go, 'Hey, superintelligence is coming and it'll be able to do things that no human can do," Field told CNBC's "Squawk Box." "I have a harder time believing that we're going to approach that really quickly right now, b

Spotify Made a Huge Mistake With AI

While Spotify users worm their way through a maze of AI-generated slop, the streaming giant's executives are dealing with an exodus of musicians after CEO Daniel Ek was working on a massive investment into an AI military weapons firm.

Google is experimenting with machine-learning powered age estimation tech in the U.S.

Google is testing a machine-learning-powered tech in the U.S. to determine the age of users and filter content across all its products accordingly. The company said it will consider data from Google accounts, including types of details users have searched for or categories of videos they have watched on YouTube, to determine the age. If the company’s tool decides that a user is under 18, they would get an email with details about how Google products might change for them. For these users, Goog

Amazon Throws Money at ‘Netflix of AI’

Amazon poured more than $1 billion into its streaming series The Lord of the Rings: The Rings of Power, only for it to get a pretty tepid reception. So Amazon appears to be going for a new approach to streaming content: If you think you can do better, prove it. According to a report from Business Insider, the company is funding an AI streaming platform called Showrunner that, in theory, will let people create their own shows using generative AI tools. Showrunner is the creation of Fable Studio,

Josh Hawley Says Trump Tariff Rebate Checks Won’t Go to ‘Biden Voters’

Sen. Josh Hawley (R-Missouri) recently introduced legislation that he claims is designed to allow Americans to “benefit” from Trump’s tariff scheme. Now, he’s giving everyone good reason to believe that his ploy to send rebate checks at a time of rising inflation is just a political stunt. The administration’s tariffs are unprecedented in modern economic history and are currently generating revenue for the U.S. government by taxing U.S. businesses on their imports. Critics have noted that the a

Trump administration's digital health tracking system gives tech giants access to medical records

Open source BOM management (for me)

Since graduating from university I’ve gotten more and more into embedded software development. This has even spilled over into designing PCBs (printed circuit boards) for my embedded devices to sit on. Initially I had assumed that the leap from software to hardware design would be insurmountable without any formal education but it turned out to be quite enjoyable. It turned out that the problem I’d be facing wasn’t a technical one, but of an organisational nature. Designing circuits Designing

The Trump-Crypto Honeymoon Is Over

As with any fledgling romance, Trumpworld and big money cryptocurrency interests were bound to have their first fight at some point. It was late June heading into July, and two highly anticipated bills were in the pipeline to help fulfill President Donald Trump’s promises to make the US the “crypto capital of the planet” and usher in what his supporters believed would be a “golden age” of digital assets. Congress had one shot at passing something before the August recess. Coinbase, the cryptoc

Déjà vu? T-Mobile may be changing your plan whether you want it to or not

Within weeks, the company reversed its stance amid growing complaints, claiming the move had only been a test . Two years later, it seems the company is at it once again. Several T-Mobile customers have taken to Reddit to complain about a new email making the rounds. The message informs recipients of a plan change set to take effect on August 13

Figma’s IPO price hit a $19.3B valuation out of the gate

Figma will begin trading on the New York Stock Exchange on Thursday in one of the most anticipated IPOs of 2025. The IPO is 40x oversubscribed, VCs confirmed to TechCrunch and Bloomberg previously reported.

So it should surprise no one that Figma, which offers design software, has priced its initial shares at $33 per share, above its previously announced range. On Monday, the company sa
