Well, llms are way more stupid, doing things that even most juniors wouldn't do (and then you don't give PROD access to new junior hire, do you... most people are super careful with llms and simply don't trust them and don't let them anywhere near critical infra or data - thats seniority 101).

Which fundamental limitation do you mean? I haven't seen anything but slow, iterative improvements. Sure, if feels fine, turtle can eventually do 10,000 mile trek but just because its moving left and right feet and decreasing the distance doesn't mean its getting there anytime soon.

Parent mentioned way harder hurdles than iterative increments can tackle, rather radical new... everything.
