Anyone else unemployable?

I see all these posts of people talking about should I go back to my job that has comp of $1mil a year? Yes, duh, obviously make that money for a few more years.

I made all my money in a super small industry and everyone I knew from it road the train and is done. Im at about $7m at age 32. But the stream has dried up. I couldn't get a job doing it if I tried. Shit, i couldnt get a job that paid $100k anywhere because the experience isn't relevant to anything. So I was forced into FIRE. I manage my investments but that only takes a few hours a week. I could sink it all into a physical business but thats gonna be a ton of work and I'll be lucky if it beats VTI. Not really sure what the hell to do next
