Came here to say this.

I even see the mindset spreading to other activities, like writing an abstract, paper, proposal or preparing slides:

I regularly (more often than not) see students using their supervisors as "CI-chain", submitting iterations with lots of stupid errors, half-baked sentences, unclean structure... because they learned to hit CTRL-b and see what comes back.

Of course there are reasons to talk about half-baked ideas, but if your task is writing a proposal or a section, you should at least be happy with what you wrote before you send it to the Prof, you're wasting his time.

But I also want to say that CI, unit tests and quick iterations are still helpful, even if you know how to approach a problem (i.e. think, research, draft, test, revise, etc.)
