He points to a real problem, but the solution is - what? We are not in a position to say "efficiency must stop", all we can say is ~"this efficiency drive has serious drawbacks" - which we can say in all perpetuity to no avail.

I'm wondering if this is might be a problem of "incomplete models". Defined such, the human need for "inefficient gaps" in their work could be factored into the models, and we might get something that resembles a less controlled mode of production again, which doesn't burn out the workforce.

But I wouldn't hold my breath.
