LLMs have changed completely the time economics of coding. Things that in the past you would never touch because they would not worth the time investment of yours, today can be almost be done in one shot by LLMs.

I built a TV OS slideshow app for both photos and videos (as far as I know all the apps just go through photos).

I have no experience in Apple OSes development and in the past it would had taken me at least a week to just read enough documentation to get started.

Now? It took me 3 hours of iterating with an LLM to start from scratch developing and publish the app.
