I feel like GPU is massively parallel but still somewhat sync, but I’m not sure.
But what I think about the article is that it mixes a lot of wishful thinking into reality. There were other CPU architectures, including ones without synchronisation, and most of them never left research. In part because current architecture is abundant, but I think that also because making something complicated work async is quite hard.
Yeah, there are maybe a couple of reasonable ideas like using background and making comments stand out more, but that’s it. Especially weird is the idea about light theme not being used because of syntax highlight
