Ask yourself `what does everybody want/need? (Hint it's not AI) Two (of many) possibilities; accommodation & food. One could investigate previous examples where startups began small and made history. Then I suggest you may need at least 2 of these: #1 A gimmick #2 Good luck #3 $$$$$$.
There's plenty of people doing accommodation and food. Or anything else with high demand. The profit margins are tiny because of this, aka red ocean. More of these don't always make the world a better place; you just end up fighting with a smaller competitor, while Big Corn rakes in the profits from the economy of scale.
and add the 3rd answer as well: everyone wants money too. Make something to help make people money. Trading alerts, charting tools, stock market aggregators, crypto aggregators, anything that can push people in that direction
