You still have your career and can get another job somewhere else. If your whole industry has collapsed so you have no alternatives, then that's a risk to prepare for in your general life plans. The world doesn't owe you comfort and security but you can easily create it for yourself if that's what you want. Also, obviously don't work at a crypto startup if you want that either!
I've done this for myself. I can't be fired, and I have 3 different "career" directions I'm going in at the same time. I'm not a high flier in any of them, but at least one is bound to always be available. That's comfort and security.
Teacher is a fairly safe fall-back. I also happened to get lucky building a succecssful commercial software product, and have another degree and a little experience in engineering. I'm not overworked but I should make it clear that I'm not senior or particularly successful in any of those fields, buy also have no worries about money.
