Many issues have been pointed in the comments, in particular the fact that most of the things that antirez speaks about is how "LLMs make it easy to fill code for stuff he already knows how to do"

And indeed, in this case, "LLM code in-painting" (eg let the user define the constraints, then act as a "code filler") works relatively nicely... BECAUSE the user knows how it should work, and directed the LLM to do what he needs

But this is just, eg, 2x/3x acceleration of coding tasks for good coders already, this is neither 100x, nor is it reachable for beginner coders.

Because what we see is that LLMs (for good reasons!!) *can't be trusted* so you need to have the burden of checking their code every time

So 100x productivity IS NOT POSSIBLE simply because it would be too long (and frankly too boring) for a human to check the output of 100x of a normal engineer (as long as you don't spend 1000 hours upfront trying to encode all your domain in a theorem-proving language like Lean and then ensure the implementation is checked through it... which would be so costly that the "100x gains" would already have disappeared)
