It's moving pretty quick.

Yes, they're an early adaptor/implementer of the recent pyproject.toml standards.

As someone that is fine on poetry for a few things, is there a good pitch deck on why I should change over?

The best pitch deck is spending 5 minutes playing with uv and trying out installing the dependencies for your project.

It’s hard to demonstrate the speed difference in a pitch deck.

Fair. I don't even know how long that takes for my projects. I presume I've been fortunate that that is not one of my long poles, as it were.

Hopeful that a lot of this will be even more resolved next time I'm looking to make decisions.
