You mean the big companies who still haven't moved away from abominations like SAP and Oracle? The ones where you require twenty approvals to get a small pilot done? Instead of moving to saner and cheaper alternatives, they would just say, "hey, why don't we just start making our own software?" Every effort like this—if it had any takers—will fail spectacularly.

I get it people are skeptical about the future. But I can't imagine any scenario where people would like taking responsibility of building and mantaining their own software for everything vs. paying marginal amount of money (relatively speaking) to let someone else take the headache.
