I think I'd broadly agree here. I would just add two additional thoughts:
1) the rise "intellectual property" is putting a damper ( by definition secret in its impact) on innovation, at least in California. The largest companies like it that way. So one sees more of the garage startups being devoted to entertainment and other non-world shaking stuff. If today one announced some new physical device for sale that had any amount of cool sophistication, the ground would begin to shake from a tsunami of IP attorneys and patent trolls running to file suit against the new gadget and its inventor. The IEEE ran an article a few years ago on how, when one actually quantifies the rate of truly new technology, things have been slowing *down* for 30 years, not speeding up as popular wisdom holds.
But I agree with the core point, the vacuum to be filled by new tech is just not that large for most people. The biggest unmet need for fully employed people is sleep.
2) Regarding highly trained providers of services, so far so good it's true. Even here I wonder if we'll see some turmoil. Physicians are being second guessed ("helped") by software for diagnosis, especially in larger settings where protection against lawsuits is critical ("the diagnosis was confirmed by the IntelliDoc distributed supercomputer, your honor...we fail to see how negligence can be demonstrated here"). I can see how ultimately doctors could be downgraded to Toyota factory style Anban technicians, whose main task is to hit a halt button if things seem to be going off track.
And man, the areas of investments and management are over ripe for picking by machine intelligence. Today equity and hedge fund managers are paid shocking amounts, and in return they rarely beat the broad market over 5 years. How long will people tolerate that? Conventional MBA type managers are in a similar situation, they add a lot of expense to keep around, but in modern organizations they decrease efficiency and value, not add to it, so one sees companies like Google seeking to shed them wherever possible. The practice of "management- less organization" is starting to appear on overviews of Silicon Valley waves in the Early Adopters column. So even among service providers in high tech economies, there's reason to look over one's shoulder. Even me.
If I were to propose an adjustment, I think I'd dwell a bit more on the advantageous position of "owners." If one owns a large portfolio of real and intangible assets, all these trends make you better off. The rest of us , anyone who uses their hands or head to earn a living, or is a hapless creative (artistic or technical) is in a bad way I think.
