It does! Working like Google is like that but having had decades to build that dream, using the resources that only a megacorp could bring to bear in the problem, and in a monorepo. The fact that it's a monorepo is not to be dismissed. git doesn't work for monorepos.
Codespaces is like CitC; I haven't been a Google since the rise of AI so I can't comment on how the internal equivalent to Copilot is; Actions is very primitive compared to what Google has, but yeah, you can see where it's going. it doesn't compare right now but it could, eventually.
