uv replaces pip (and venv, and pipx, and more), not conda. If you want a uv-equivalent that replaces conda, then look at pixi: https://pixi.prefix.dev/
Sure, it replaces pip, but _we used conda_ for env management. And the slow part was still _dependency resolution_, much like pip.
Was there a better option? I’m sure. Choices were made. Regrets were had. Switching to uv was a huge improvement for our purposes.
