You seem to rely on “emotional” and “irrational” abilities of humans as the key for humans to staying relevant, all get great useful jobs that computers cannot do, and remain in charge in a world of increasingly smarter computers.
You state “Luckily, our ability to think irrationally gives us humans an edge in creativity.”
You are wrong.
Computers very easily can be given the gift of irrationality. In fact, computers have already demonstrated the ability to invent and discover new things by combining randomness appropriately with other actions such as filtering for positive results from a large number of random or partially random directions in thought. Easy for a computer to do.
I suggest a different approach for humanity to remain relevant as follows: we live in a carbon based world wherein we have evolved fitness for the carbon environment. For example, we can make more of us by removing carbon, nitrogen, from the air combining with water (plants) and reproducing on a planet with open source conditions for our own multiplication. We evolved ways to cope with hazardous oxygen, UV, repair systems etc.
Silicon and related semiconductor life requires a more difficult set of metallurgy conditions.
As machines and humans compete and possibly war for survival on this planet, humans need to focus on becoming more fit for their particular niches. We need to get back to the land, to building self sufficient communities wherein each individual has a role in a carbon environment, actively using and modifying that environment, wherein machines cannot displace us.
We do not have a unique ability to think random thoughts and to act based on physiological instincts. Computers easily can do the same, we just dont need to evolve computers to do such things, yet.
