I would suggest that to "improve ... humanity in general" you actually need to redefine the production process, the consumption process and what gets consumed.
If you keep the keep the same assumptions and automate more, all you wind-up with is people lose their jobs and become homeless because there's no new activity for them to do. And his example of increase production shows how that doesn't necessarily improve things. Of course, any increase in production does redefine all this stuff, it has to. The question is whether it redefines them enough.
