> One of the sad things I've learned first hand about the tech business is that even profitable small products are just not interesting to billion dollar companies. You need large enough revenues to make a splash as well, and these tiny MCUs selling at quantities of 10K here or 20K there just isn't enough to make Intel want to work for it.

This is one of the core thesis of the Innovator's Dilemma: the multi-billion dollar companies aren't interested in competing to serve your niche application.
