It’s AI but a specific use case of AI: an android at home to take care of the housework. Cleaning my dishes, doing the laundry, vaccuming and putting stuff away where it belongs are obvious use cases. But also:

• Go through your fridge and throw away everything that has expired or gone bad.
• Take care of your cat while you’re away on vacation.
• It’s your personal fire fighter.
• It paints your house or does any kind of house maintenance.
• Let’s say you’re in the middle of playing a board game on your dinner table but need to put it away for the night. Ask the android to memorize everything and put it away. The next time your friends come around to play, it can place everything in exactly the same spot.

Possibilities are endless.

This is the key to so much. Worried about Nestlé monopolizing freshwater? With nuclear fusion we can just take any old seawater and remove the salt. Worried about the war with Russia? With nuclear fusion we can become independent of all gas from Russia and cut off one of their biggest income sources. Lots of special materials are expensive because electricity is expensive - with nuclear fusion electricity is practically free. Over time we can get rid of any coal plants etc. that produce CO2.
