>until 1) software is saturated
Software has been saturated for a long time.
There are a bajillion apps on the app store that get little to no recognition. Most software startups fail to find a foothold and go under. An uncountable number of FOSS projects have been seen by at most a handful of people, and even fewer who have used/cloned the code.
that doesn't imply software as a whole is saturated.
does the world use more or less software YoY? (LLMs counts as software btw.)
the differentiating factors have changed but the underlying demand has only increased.
