Some of this talk makes me nauseous. I mean I know this about college grads and fields in general, but this brings it to the forefront. Do current or recent CS majors really pick it only for a “good job”, because CS seems hot right now? Because you can go ahead a read articles on why there’s going to be a million CS jobs and no CS grads, so you pick CS, and then in 6 months read an article on why CS jobs will be outsourced and finance is the place to be. And your CS theory classes were just so hard… so you change majors to Finance, or others. To be frank, if that is a college sophomore’s feelings it’s pretty likely they will not shine very bright.
You major in CS because you like it / love it. Not because of pay, not because of jobs, not because of anything else. Then anything about age, burning out, not finding a job, not having enough money all falls to the wayside.
If you don’t like programming and computers, trying to do CS because of “tech startups” and jobs is pointless. Because everyone who loves it will far surpass you.
