Yeah, the idea that there is somehow Unlimited Demand to tap is just woefully underexposed to business realities. Demand at most businesses is a river, not a municipal waterline with a spigot at one end. It ebbs and it flows, and building for a hypothetical high-demand future is what you do when you have venture capital expecting it of you--not when you're building a "small business" (or even a medium to large one, if you want to be resilient).

It is, however, a really convenient excuse for people who don't regularly think about how people who don't work "above the API" actually exist in the world.

Seems most people miss this. If anything businesses will increase their profits instead
