Fintech? What Kind of Rabbit Hole Do You Go Down?

I just don't think I've smart enough to understand a lot of what like other people are doing in more esoteric spheres off the world or maybe just things that I don't have expertise in. So often I do, often I kind of go down, I'll see like a random employee loyalty program startup. And I'm like, oh, this is interesting. What's that about? If it's a bit more technical in the domain, I don't understand,. I often just end up quitting, probably just because I often just can't understand it.
