On performance: 3.13 removed the GIL and added experimental first-party JIT (like PyPy). In two years I bet we’ll be seeing v8 level performance out of CPython.
I bet we’ll be seeing python compiled to JVM of getting JVM levels of performance. Much better than v8
The sticking point for me is the way tools like uv and poetry build everything around the idea of a "project". I don't want a separate environment for every project, and I don't want to start by creating a project. I want to start with an environment that has stuff in it, and I start fiddling around, and gradually something comes together that eventually will be pulled out into a separate project. From what I can see…
I think you're basically suggesting that you'd have a VM or something that has system-high packages already preinstalled and then use UV on top of it?

> But then I remember that Python is dog slow compared to other languages with comparable ergonomics and first-class support for static typing, and...idk it's a tough sell. Post like these aptly describe why companies are downsizing in lieu of AI assistants, and they are not wrong for doing so. Yes, Python is "slow". The thing is, compute is cheap these days and development time is expensive. $1000 per month is consi…

why is a uv README the top post on HN??

You can't just create yourself an "everything" environment with UV and then experiment with it? Honest question. I think you're basically suggesting that you'd have a VM or something that has system-high packages already preinstalled and then use UV on top of it?
I don't see anything resembling "environments" in the list of features or in the table of contents. In some sections there is stuff like "When working on a project with uv, uv will create a virtual environment as needed", but it's all about environments as tied to particular projects (and maybe tools).
You can use the `uv venv` and the `uv pip` stuff to create an environment and install stuff into it, but this isn't really different from normal venvs. And in particular it doesn't give me much benefit over conda/mamba.
I get that the project-based workflow is what a lot of people want, and I might even want it sometimes, but I don't want to be forced into foregrounding the project.

It unblocks that workflow, that's why it's so great. You can have a single script with inline dependencies that are auto installed on execution. That can expand to importing other files, but there is very little setup tax to get started with a script and it does not block expansion.

Could it be that you’re just used to separate environments causing so much pain that you avoid it unless you’re serious about what you’re doing?
