The "new ideas of its own" was too strong, and I came across as far more negative about uv than I actually am. It is a great tool, and overall it's a big positive for the python world.
I was just thinking of poor pipx who has been doing what uvx does for over 6 years, and were first to implement PEP 723 by quite some time. Whenever I hear someone say "Oh look at what uv can do!" I want to shout "pipx did it first!" - but I don't... mostly because I've switched to uv.
