I've written similar warnings and concur on your conclusions. One piece I wrote was Automaton's Law—anything that can be automated, will be automated. Another was on the Programability of Matter where I liken robotic manufacturing to DNA building biology which DOES lead to evolutionary pressures on humanity. I would enhance Path 3 to intelligently and ethically incorporate AI into a complex societal life support system to run our cities and farms efficiently, create new materials and usher in the Golden Age of medicine, not replacing jobs but freeing people for better things than jobs. After all, we are the sentient ones who can enjoy it.
