Ask HN: What are your views on using AI in software engineering?

If you are an experienced SOFTWARE ENGINEER 5+YOE and you have integrated AI in your daily stack, like for real production grade SAAS delivery - for any part of it for ex. UX, copywriting, vibe coding, testing, etc.

I am looking for your insights.
