Git worktrees are a huge unlock with agents.

They used to be hard to understand how to use, but LLMs are great at them.

Giving agents isolation, so if they blow up something, they don't blow up everything else, allows them to move fast.

A powerful piece of infrastructure will be containerization++.

Not just containerizing the code, but also the data and resources.

Imagine if you had a copy-on-write filesystem and data layer.
