I'M SCARED ABOUT BIOLOGICAL COMPUTING

Summary from the TLDR newsletter

A few months ago, a company released a video showing how it grew neurons in a lab and got them to play DOOM. The scientists fed visual data to the neurons, which reacted to that data in some way to play the game. This could mean that the company built a human biocomputer and then put it into a simulated hell, playing the same game on a loop. While it was 'just a science experiment', the biocomputer had more neurons than a jellyfish or a worm. There's a large commercial incentive to continue developing the technology, but the ethical implications are still unclear.
