I didn't say robots are more energy intensive than humans, I said they are energy-wasting machines that are energy-intensive to produce. Robots do not grow on trees. Nor do they grow inside wombs. Their existence depends on non-sustainable artificial systems that bypass and ignore ecological realities for the sake of... hell if I know what the point of it is. Machines - robots or otherwise - are manufactured using mostly non-renewable resources without much if any consideration to end-of-life use. In ecological systems, nature just recycles everything and uses renewable sources. Humans ignore that constantly, and it would be so with robots as much as it is already with things like cell phones and computers. That isn't a sustainable model. It does not make sense to waste energy making energy-wasting machines when sustainable tech (or non-tech) already exists that does the same thing, especially in the present era. It's really too bad that appropriate tech movement was killed off. We need it now more than ever.
The typical human consumes far more non-renewable resources & energy than a robot.
Remember that each human needs a home, transportation, communication
devices, food, etc, etc. over its lifetime (most of which isn't working).
A robot is built once, & thereafter needs nothing other than energy
occasional repairs.
Just look at these dedicated honest workers (who can be painted in any color)....
No transportation (car, or bus) cuz they remain on the job.
No food, no vacation travel, no entertainment, no house, etc.
No break room, no union hall to build, maintain & heat.
Robots are on the whole very sustainable compared to humans
with their cars, houses, TVs, pools, RVs, motorcycles, monster
trucks, boats, kitchens, bathrooms, sofas, hot tubs, etc.
