The problem is git is three things, a command line interface, a wire protocol, and a database format, and you can't replace all three at once if you want to gain any acceptance. So you have to chip away at the individual pieces. The real problem though is that AI makes version control invisible because the agents are capable of producing the artifacts. AI makes git's data model all wrong. What you want is then a way for AI to be able to make, say, 1,000 views into the codebase, cheap. That involves spinning up VMs/containers and is a much different problem than hey, let's make github2.com.
