I guess my impression using these tools daily is that it hasn't diminished the need for my own technical expertise. The conversations I have with it are highly highly technical, and to me the insights come from both sides, I see things the LLM doesn't, and the LLM sees things I don't. It writes a lot of bugs that I have to spot, and writes designs that aren't correct. (This isn't a criticism, I do the same). I think the ideal world version of this stuff is complementary, but the current insane bubble economics mixed with the insane religious fervor make that unpalatable to the leading AI companies. (Like, I think Sam Altman said that anything below a trillion dollar IPO valuation is a "non-starter".) So, "nice coding tool", even if that's the BEST and most realistic outcome, is just not going to do it for them.
