I really have trouble imagining a world in which a drastic decrease in the cost of software development doesn't lead to a drastic increase in demand for custom software.

I remember when I worked at a design agency, we spent so much time trying to select project management software, but nothing ever really fit our specific needs. We never considered trying to commission something custom, because a decade ago, that would have been totally nuts for a 20 person company. Nowadays I absolutely think we would have just made something in-house.

I was a teacher at a K-12 school last year. The admin team was trying to select new curriculum mapping software (a system which lets teachers see what kids are learning across different grades and subjects at various levels of granularity). The standard solutions for this all suck. The admin eventually decided to just create something custom, using AI.

I suspect that every company is going to want bespoke systems which are perfectly tuned to their needs, once it becomes financially viable to do so.
