First comment I've posted here, been lurking for a while.
Been running uv in every AI/ML project for the past year -- the speed difference when resolving large dependency trees (PyTorch + transformers + a dozen extras) is genuinely significant. It's one of those tools where you forget how bad pip was until you have to go back.
Coming from a Rust background I have a lot of respect for the implementation decisions that made that speed possible. My main concern isn't feature direction -- it's that the team culture IS the product right now, and that's harder to preserve than a codebase. Cautiously watching.
