Here again, I think, is a somewhat tech-centric view on economics.

There is only a finite amount of automation demand, simply because human labor exists.

Inside of our tech bubble, automation simply means more "functionality" per person per time unit. What took 10 devs a year yesterday can be done by 5 people in 6 months today. That's all five and dandy, but at some point, software clashes with the hard reality of physics. Software doesn't produce anything, it's often just an enabler for physical production. Lube, or grease.

Now, that production obviously can be automated tremendously as well, but with diminishing returns. Each generation of automation is harder than the one before. And each generation has to compete with a guy in Vietnam/Kenia/Mexico. And each generation also has to compete with its own costs.

Why do you think, chips are so incredibly expensive lately? RND costs are going through the roof, production equipment is getting harder and harder to produce, and due to the time pressure, you have to squeeze out as much money as possible out of your equipment. So prices go up. But that can't go on forever, at Stone point the customers can't justify/afford the expense. So there's a kind of feedback loop.
