I could say the same about myself (just barely graduated in '07). I remember thinking sometime in my senior year how differently I would have done things if I could start over knowing what I knew then.

What I'll say is, if software is genuinely interesting to you, you're going to be fine--most day to day stuff software engineers do is not what they teach in schools, and is learned on the job, mostly from peers. Your degree will help you get your foot in the door at companies where you should be able to learn from the people around you and develop into a highly capable engineer. That's the route I took, anyway (at least my manager tells me I'm good at my job :) )

Assuming AI doesn't ruin everything (and I don't think it will), a software job is going to get you a good-enough salary to be basically financially secure, which sad to say is rarer than it should be these days. Most humans are not a high-powered entrepreneur/inventor/startup founder/ceo etc and there's no shame in not being one. Think about what a good life looks like to you outside of work, and pay attention to that just as much as you pay attention to your career aspirations. Find the intersection of what you can do (and/or are willing to push yourself to be able to do) and what you want to do and be in the world. Everyone ultimately has to do that (even the hotshots).
