I'm 39 and feel like it's definitely too late for me. I'd be 42+ by the time I'm done and with the way the economy is and the job market in general I don't think there would be any positive for me to go through that expense.
I basically just missed the boat, all my friends went to school for computer science when they were ~20 so they're safe now and make an absolute killing. If I were to try that now I'd just join the like millions that can't find work in that field... For the last 5 years every single day the news has been "omg a recession is coming, it's coming, it's definitely coming like tomorrow! Be afraid, it's coming!" So I never left my shitty factory job, but now I just feel stuck...
