>I've found the problems that biologists cause are mostly 1. Not understanding dependencies, public/private, SCM or versioning, making their own code uninstallable after a few months

That's not on them though. That's on the state of the tooling in the industry.

Most of the time, dependencies could just be a folder you delete, and that's that (node_modules isn't very far from that). Instead it's a nightmare - and not for any good reason, except historical baggage.

The biologists writing scientific programs don't want "shared libraries" and other such BS. But the tooling often doesn't give them the option.

And the higher level abstractions like conda and pip and poetry and whatever, are just patches on top of a broken low level model.

None of those should be needed for isolated environments, only for dependency installation and update. Isolated environments should just come for free based on lower level implementation.
