I think it's easier for good engineers to be good, perhaps. For example, I think property testing is "good" engineering. But I suspect that if you took a survey of developers the vast majority would not actually know what property testing is. So is AI really of any use then for those devs?
Internet enabled instant to access to all human knowledge as well as instant chit-chat across the globe. Guess what humanity choose to drown itself in?
So combine both facts here in context, with human nature, and you ll see where this will go.
I think it depends on your process. Problems that require creative solutions are often solved through the act of doing. For me, it's the act of writing code itself that ignites the pathways and neural connections that I've built up in my brain over the years. Using AI circumvents that process, and those brain circuits go unused.
I love that I don’t have to look thru SO looking for a problem that’s kind of like the one I’m having. I have a problem solved based on my exact code taking my entire code base into account. And if I want a biting sarcastic review of my many faults as a software developer, I can ask for that too.
