I can run `uvx sometool` without fear because I know that it'll take a few seconds to create a venv, download all the dependencies, and run the tool. uv's speed has literally changed how I work with Python.

I wouldn't say without fear, since you're one typo away from executing a typo-squatted malicious package.

I do use it on CI/CD pipelines, but I wouldn't dare type uvx commands myself on a daily basis.
