>How do we separate business logic in a self-contained way that can be independent of hardware and (from a certain level) software?

Come up with programming languages with limited domain specific functionality that don't allow you to do funny machine specific things. (or even ordinary things like pointers)

Use the restricted languages for business logic and have a second language to do the plumbing.

Or just target a generic x86_64 virtual machine.

So all critical software in Python or JS? Not so sure about that. I get the idea but think having strict code guidelines might be more effective than choosing a more restrictive language.

No no, restricted, a programming language that can't do a lot of things. A language that can only do business logic kinds of things.
