I agree with the second part, 90% of apps are just a vague rehashing of 100 other apps, very little novel software ever gets written, especially at the component level. The point being that if you want to create truly novel systems you best know how to program, even if an LLM is writing the less novel parts of that system.

If we're smart about this, maybe it means we get to do novel work a little more frequently. That said, I fear that a lot of people don't look at every single LLM output and think "Eh it's workable but it doesn't spark joy" and anyone who doesn't think that is likely going to be seeing their QOL decreasing. At that point your time might be better spent learning how to make Molotovs.
