I've done the meetup thing. I'll say that most tech meetups have been a total waste of time. "I have an idea for <x>. Could you be my tech co-founder and build it for nothing?". Please.
The other aspect of meetups is that a lot of them are loud drinking parties. I don't drink. No, not some prudish thing. I just don't drink. The stuff doesn't attract me at all. And, of course, if I my intent is to meet people I kinda want to be able to hear them. So driving to a meetup an hour away, at a bar, with loud music and booze isn't my idea of something productive. Could be wrong.
Another thing I didn't mention is the personal email to someone at some company, being honest about some real connection why you and them should be together, not in response to a job listing but just in response to why you'd think they're a good fit, or praising them honestly on something they do. I at least tend to get responses, if nothing else, from these outside-the-box attempts.
If ANY of those work, please let me know so I can follow my own advise.
As for school, only go if what you want to do is to learn more and if you think that's the way to learn.
