Bret Victors Dynamicland research project/group, although there is not very much to follow publicly, but the occasional glimpses are always full of very interesting ideas.
Super excited about WASM / WASI as a standardized way of running microservices. Like cloudflare workers.
Spacetime as a data structure
Do you mean a data structure to model spacetime and gravitational bending of it, or do you mean using spacetime to store regular data?
It's basically as Python keyword 'as' implies: spacetime and whatever it contains including gravitational bending being a data structure (one of many), which obviously is not just another object in spacetime, but spacetime itself. There's one cognitive neuroscientist, a few physicists and mathematicians who're developing this.
