If nothing else the HN mantra is not "That's how we've always done it."
I've watched people use co-pilot but and I'm not 100% convinced it's a good thing but I'm open to it. The problem I've seen is that in some cases it generates some really bad code, code that could've been replaced by usage of a standard library.
What I think it's really good at is helping to learn new languages. Getting idiomatic code generated, even if you throw it out eventually is a great way to get a feel for a new language without having to jump back and forth between the editor and the browser.
I'm not against the idea of ai coding tools on premise, but it did strike me as kind of funny to imagine someone using two such tools at the same time.
I'm more of a minimalist, and would generally prefer to have lean tools which get out of my way. The idea that every keystroke involves a back-and fourth with a server, and that my basic coding workflow would need an internet connection is not something which is super appealing to me personally.
