I bought a portable unit last year and used it for the hottest days, as I was working from home in a small room which heats up quickly.
I also bought it for safety reasons, we are for people in our household and in case a long lasting heat wave comes we at least have the means to cool down one room for the night where we all can sleep.
Half of what you say is true. But robots are expensive, in many cases way more expensive than child labours around the world. And while it’s possible to have robots do grunt work, true AI is still far away, like several decades.
