Tesla sales are down considerably worldwide. Banks say that Elon Musk has created a 'code red situation' by overinvesting his time in the US Department of Government Efficiency. Tesla's brand has taken a hit due to Musk's public persona and many customers have returned their vehicles to distance themselves from him. Musk's bet on the future of self-driving tech over cheaper vehicles has lowered investor confidence in his vision. Musk announced that there will be a live company update during the earnings call today.
2025.04.22·futurism.com·3 min read·TLDR It was nearly a year ago when US District Judge Amit Mehta ruled that Google had acted illegally to maintain a monopoly - over the next several weeks, lawyers for Google and the Justice Department will face off again to determine what penalties will be levied against Google. Google maintains that it will appeal the decision once the remedies phase of the trial is complete. The company argues that the Department of Justice's proposed remedies would hurt American customers, the economy, and US tech leadership and innovation.
President Trump's pledge to make the US a bitcoin superpower has set the stage for crypto to become more intertwined with the banking system. Several crypto firms are planning to apply for bank charters or licenses. Some are interested in national trust or industrial bank charters, which would enable them to operate more like traditional lenders, while others are after relatively narrow licenses that would allow them to issue stablecoins. Firms that obtain a bank charter will become subject to stricter regulatory oversight.

2025.04.22·mackenziemorehead.com·15 min read·TLDR Python 3.14, which will ship in late 2025, will contain a feature called template strings (t-strings) that opens the door to safer and more flexible string processing in Python. f-strings have become a very popular way to format strings and are being used for everything - even when they shouldn't. t-strings are a generalization of f-strings that must be processed before they can be used. This post provides a quick overview of how to use the new feature.
2025.04.22·davepeck.org·5 min read·TLDR Events are a useful mechanism for transmitting state and data among application resources, but they are a miserable experience for developers and operators alike. The event-driven approach was necessary early in the decade but it isn't any longer. Today's modern abstractions mean that developers don't need to learn the unique quirks of low-level infrastructure or understand the overall application architecture just to build or enhance their part of the application. Event-hidden grants engineers new powers while simplifying engineering. It enables developers to build feature-rich, scaled, and distributed applications without having to interact with events, queues, and the industry of patterns, frameworks, and consultants that came with them.
2025.04.22·skiplabs.io·6 min read·TLDR While many are spooked by large language models, college freshmen should still study computer science - being supported by AI tools is not a substitute for mastery.

OpenAI is currently a $300 billion for-profit company governed by a nonprofit board. Investors began demanding that the company shed its quasi-nonprofit status after Sam Altman was fired in November 2023. The company has been trying to balance the desire to raise capital and build the tech and stay true to its mission since its beginning, but the latest move is an attempt to separate these things. This article discusses the hurdles that OpenAI has had to overcome to make the transition a reality. OpenAI's board will decide on the company's future and evolve the OpenAI nonprofit well before the end of 2025.

A series of messages from April 2022 showed how Mark Zuckerberg had concerns about Facebook's 'Friends' structure and format being outdated as every other major platform focused on 'Following'. He had considered ditching the Friends format and even suggested deleting everyone's Facebook friends and having them start again.

2025.04.21·techcrunch.com·4 min read·TLDR China's Gobi Desert reactor, a two-megawatt research unit engineered to use molten salt as a fuel carrier and coolant, achieved 'full-power operation' last June and its team recently succeeded in reloading the reactor while it was powered up. The Thorium-powered reactor design offers a more accessible but less weaponizable alternative to uranium. Using molten salt carries far less risk in the event of a meltdown compared to water-based systems as salts can carry greater loads of thermal energy at much lower pressure. The fuel is already molten - in the event of a breach of a vessel or pipe, it will just leak out and freeze rather than explode.

China wants to be a world leader in humanoid robots by 2027 - its authorities have lavished support such as subsidies, talent bonuses, and tax breaks on robotics companies. The first robot finished the race after two hours, 40 minutes, and 42 seconds - the human champion completed the race in one hour, two minutes, and 36 seconds.

It can be downright dangerous to accept AI-generated output at face value - unchecked AI-generated code can massively amplify technical debt. Many early vibe-coded projects look good on the surface but hide a minefield of issues. Context, scrutiny, and expertise are required to discern the good from the bad - the hype of 'AI magic' needs to meet the reality of software engineering principles.
2025.04.21·addyo.substack.com·21 min read·TLDR Cursor and Windsurf aren't just good developer tools, they could potentially become the AI-powered workspaces of the future. OpenAI might want Windsurf because of the usage data from users interacting with models, which could help the company's models catch up to Anthropic's on coding benchmarks. The competitive landscape is now getting messy - Microsoft (which makes VS Code) is now directly competing with Cursor and Windsurf (based on VS Code) through GitHub Copilot's new agent mode, but it is heavily invested in OpenAI, which is invested in Cursor and is now buying its biggest competitor.
2025.04.21·subtle.so·3 min read·TLDR Emerging technologies like artificial intelligence, genetic profiling, and personalized therapies offer a pathway to rethinking how coronary artery disease (CAD) is addressed. Efforts over the past few decades have focused on risk factors like high LDL, smoking, or diabetes as proxies for CAD, but these often sidestep the core issue of atherosclerotic plaque buildup in the arteries. Plaque type, volume, and progress are details that predict heart attack risk more precisely than cholesterol levels alone. New approaches are using imaging enhanced by AI to detect plaque and then implementing gene-slicing techniques to neutralize genetic risks while lifestyle and medications tackle environmental factors. While cost and accessibility pose real questions to scaling these therapies, there is evidence that suggests feasibility.

Donor hearts are usually removed and preserved in cold storage, which can damage muscle tissue, reducing function and health once transplanted. The operation was possible due to a specially designed organ maintenance system that kept the donor heart pumping with oxygenated blood throughout the process. Followup appointments with the patient showed that they maintain a low level of cardiac enzyme, something that usually spikes during typical transplant conditions.
