I do agree. But I think people is focusing on speed as if it was the only important thing to measure. It may be for some people-in-suites, but what about professionals?
A friend of mine who had minor knowledge about internet (used to do wbesites in HTML with iframes back with Dreamweaver) was able to deploy a PHP app using GPT. Great! It saved him a lot of time. Now I asked him if he understood or was able to do a change and he told me that he mostly did copy and paste and asked GPT to change things for him.
Not saying GPT is going to dissappear and no one is able to maintain this, because that sounds silly, but even with GPT at your side, it's improtant to understand what's happening in case you need to do a change.
Two notes, before anyone jump to this: I am not talking about simonw particular case, he seems a developer who knows his way around Python and could do all of this by himself, it's just saving his time.
Secondly, probably in the future a LLM will be much better at coding and will be able to fix or improve your code even if you don't understand it and will be able to do an startup from zero, scale it, deploy servers, etc. Who knows?
