What would I do with “around” $44B?
Immediately start new villages made of 3D-printed 100% sustainable homes with radiant heating floors, hemp insulation and green roofs. You already know. I would give them a nice lot for people to grow some stuff. I’d subsidized rent, of course. I’d create a copy of Broadacre, only smaller.
Offices would be rare as most people would work from home. If not, there would be nice roads to use to go there where you could use a car or a bicycle, both being on different, astuciously designed paths.
There would be downtowns, albeit small ones because only those work. A main street, stores, ta-da.
I think $43B would allow me to try that, and see how much better of a plan it is than what we currently have.
Then once I know this village works, I’d made more in very different climates, to optimize the sustainability of those homes; weather dramatically changes everything about a house’s needs and infrastructures around.
Once I have a cluster of solutions, I’d scale up.
That’s a good use of $44B, I’d say.
Or maybe as someone said, I would just give each American $1M and some change for us to chill while robots now and then produce.
Either way, it would be fun.
