ideas i did pass:

1) coding assistants, coding harnesses (now could have been one of the top easily or at least have a name)
2) vector databases (it turns out most of them were indeed shit except turbopuffer)
3) compact nuclear reactors (guess what’s the next way in energy in us?)
4) home management - literally take 3d scan of a home enumerate everything autistically and vendor contractors and sell as subscription. (guess what was recently launched in bay area?)
