This is like when two years ago people said "oh yeah if these things are accelerating software development then where's all the new software??!!"
The answer then was "it still takes time, man".
That's the answer now, too!
It took time for them to accelerate the quantity of software, which is the thing these are most naturally good at, and it will take even more time for them to improve the quality of software, which has proven to be less of a superpower for LLMs than quantity is.
