I think it was mostly worth it. Some upper level classes were half baked, with a few faculty members of dubious competency. But, I did learn enough to apply myself to my chosen field.
Personally I think what you gain from education comes from three things:
i. How much you apply yourself, how much are you willing to self-study, do research, your own projects, ask question. ii. The structured pathway an educational institution gives you to learn certain skills and gain knowledge. In self-learning the problem comes knowing what to learn and in what order so that you can advance to a more advanced level. iii. People you meet. Not just networking, but the fact that if you hang out with very clever people all day long, some of that prob sticks to you as well.
Even my art degree was extremely useful, although it provided absolutely no path to employment. I don’t know what the future brings, but I have absolutely loved my current degree so far, although it admittedly very hard at times.
