TESLA WILL LAY OFF MORE THAN 10% OF GLOBAL WORKFORCE: READ THE ELON MUSK MEMO

Elon Musk sent a memo to Tesla employees saying that the company will lay off more than 10% of its global workforce. Tesla had 140,473 employees as of December 2023. Its shares have fallen 31% year to date. Electric vehicle sales are gaining popularity worldwide, but the company is facing more competition now than ever. It is also dealing with other challenges, such as logistical problems caused by Yemeni Houthi maritime attacks in the Red Sea and production suspension at its gigafactory near Berlin due to suspected arson at a nearby electricity substation. A copy of the memo from Musk is available at the end of the article.

CSS IN REACT SERVER COMPONENTS

React Server Components (RSCs) allow server-exclusive code, which can lead to better performance. However, this means that popular styling options, like CSS-in-JS libraries which rely on React's lifecycle, can conflict with RSCs. RSC's server-side focus clashes with the browser-centric nature of traditional CSS-in-JS libraries, but there are “zero-runtime” CSS-in-JS libraries that are fully compatible with RSCs today. If your application doesn't use these and already has a good “time-to-interactive” time, then migrating to these libraries is not worth it.

HONG KONG SPOT ETFS MAY ONLY HAVE $500M IN INFLOWS

Senior ETF Analyst at Bloomberg Eric Balchunas speculates that the upcoming Hong Kong Bitcoin ETFs will not have substantial inflows or market effects. The ETFs will not be available to Chinese locals, and the Hong Kong ETF market is only $50 billion. With no big players involved and less liquidity, the market will be less efficient with spreads beyond where Bitcoin normally trades. These factors and relatively high 1-2% fees make this more of a moral victory than a financial one for Bitcoin.

LIMITLESS IS A NEW AI TOOL FOR YOUR MEETINGS — AND AN ALL-HEARING WEARABLE GADGET

The Limitless Pendant is a device that records everything its wearers hear and then uses AI to help them remember and make sense of it. Designed to be clipped onto a shirt or worn on a string around the neck, it uses a beam-forming technology that can more clearly record people around the user and not the rest of the room. The Pendant is part of a system that uses data from different apps to provide users with useful information. The company plans to eventually create AI agents that do things on users' behalf.

GOT TINNITUS? A DEVICE THAT TICKLES THE TONGUE HELPS THIS MUSICIAN FIND RELIEF

Lenire is a device that treats tinnitus using electrical stimulation of the tongue. Approved by the FDA in March last year, the device consists of a plastic mouthpiece with stainless steel electrodes. A clinical trial found that 84% of participants who tried Lenire experienced a significant reduction in symptoms. While the device costs around $4,000, more than 80% of the participants in the clinical trial said they would recommend the device to a friend with tinnitus. It is unclear how long the benefits last as clinical trials have only evaluated the device over a 1-year period.
