The mantra is to find a problem [you're passionate about] and solve it for a small group of initial users. A corollary is to find an emerging technology and make it easy to use or make something related that doesn't currently exist. I say it's a corollary because I assume that whoever is working on the new technology has found a problem and is trying to solve it. Speaking about myself, I was interested in two-factor authentication and security keys. A couple years ago I saw an opportunity in FIDO2 [I was betting on a hopefully growing technology] as there was no open source FIDO2 security key. With a group of friends we decided to make SoloKeys [1]. I guess in our case we decided to make it a company vs a side project, but that's just the amount of commitment. Fast forward 1.5y, FIDO2 is implemented on all browser including mobile safari on iphone and Microsoft is pushing FIDO2 a lot. So I guess the bet was good so far. This is a long story to say that maybe it's hard to think to a problem, but maybe you can find a technology (that someone else developed to solve a problem) and you can be part of that ecosystem. Best of luck! [1] https://solokeys.com https://solokeys.com
