2. In defense of the rabbit r1: TechCrunch's Devin Coldeway finally received his rabbit r1, a small plastic cube with a screen and access to an AI service. He argues that devices like the r1 that are "weird, relatively cheap, and obviously an experiment" are something that we should rally behind, not dunk on for being what they are. Read More

3. Federal money for digital twins: Digital twins are virtual models of real-world stuff, useful for all sorts of things. You can use them to make a virtual copy of complex stuff like factories, allowing you to tinker with them without stopping production. They are also useful for helping design semiconductors, so the U.S. government is investing up to $285 million into them. Read More

Turning corpses into dirt is big business apparently: We all have different ways of dealing with our mortality. When I die, I hope that my remains are shot from a cannon straight into space.

China's tech industry sheds jobs: Much like in the United States, large Chinese tech companies are learning to do more with less. The SCMP reports that China's three largest tech companies are now 25,000 workers lighter than they were at the end of 2023.
