Me reading this as a computer scientist

Chat, are we cooked?

The trades will ALWAYS be in demand. No matter where society goes, as long as it doesn't collapse we will need running water, electricity, toilets, transportation, etc. I went to college for bio, switched to CS, graduated with business management degree and now I'm a mechanic. The hope is one day run my own garage perhaps, but untill then I love comfortably enough and know I can walk out tomorrow and find another job before I make it home.

Also consider a healthcare career. As a teenager, I wanted to do computer science/engineering, and sometimes I do wish I had stayed on that track. But now, as a nurse, I could get a job in any state in the US by tomorrow. I dare you to try to find a hospital that doesn't have open nursing positions. Even when the economy goes down, people still get sick. Even if society collapses, the knowledge/skills will be useful.

And if you don't want to change diapers or deal with blood, there are still options; I'm in psychiatry and rarely have to deal with either.
