The argument you put forward doesn't make sense. It's not a ripoff to make close to minimum wage for a number of years (and possibly take on high levels of student loan debt), all to work in a field where there is an oversupply of labour that depresses wages?
My experience is the work in academia is more interesting and intellectually stimulating than my high paying tech jobs. That would be one motivation to go the academia route instead of the tech route.
If you come out the other end of a PhD, then you have the opportunity for best of both worlds: high paying job to work on the problems you find intellectually stimulating.
Also, it is cliche, but doing a PhD does train a person in a way to think that you don't necessarily pick up in a normal job.
Having a PhD is a bar raiser, it automatically disqualifies you from a lot of jobs that don’t have intellectually stimulating problems to work on. This is all fine and dandy if your area overlaps with a hot field, but not if it doesn’t (or is then but isn’t now). Right now, 95% of the CS industry jobs for PhDs are in AI.
The thinking advantage of a PhD is really valuable, its like an extended apprenticeship with your advisor. Also, it gives you time to look at things you find interesting (well, it should, sometimes not).
Yeah fair points. I was sick of studying by the time I graduated - I enjoyed my experience at University, but I wanted to get into the private sector (probably worth mentioning that I studied business at the undergrad level, so I think a lot of that 'postgrad research' in marketing for example is suspect at best).
Ok...
