the idea is to use AI to build super productive farms and greenhouses, improve the capability to do that in urban areas, automated and super efficient transportation. but it's not just AI doing all that, it's someone who wants to start a business using AI himself to figure out how to best start up a greenhouse in his community and setup the tech infra needed including the API for people to be able to view available produce, estimates on availability, initiate trades, etc. (this greenhouse thing is just one example).

another example could be someone wants to build an ecosystem monitoring station to monitor the nearby ravine (pollution levels with rainfall and other events etc.) and air quality over time. this is just a small datapoint but if people all over the place build their own ecosystem/weather monitoring things using basic electronics ordered from the internet and all plug them in to a standard observability software system then that could provide some pretty awesome outcomes including figuring the best way to clean polluted water (because some of the places will surely have implemented varying methods of sanitizing their own water).
