You seem like a great professor(/“junior baby mini instructor who no one should respect”, knowing American academic titles…). Though as someone whose been on the other end of the podium a bit more recently, I will point out the maybe-obvious:

  Of course I can't ensure they aren't just having AI do the projects, but I tell them that if they do that they are cheating themselves

This is the right thing to say, but even the ones who want to listen can get into bad habits in response to intense schedules. When push comes to shove and Multivariate Calculus exam prep needs to happen but you’re stuck debugging frustrating pointer issues for your Data Structures project late into the night… well, I certainly would’ve caved far too much for my own good.

IMO the natural fix is to expand your trusting, “this is for you” approach to the broader undergrad experience, but I can’t imagine how frustrating it is to be trying to adapt while admin & senior professors refuse to reconsider the race for a “””prestigious””” place in a meta-rat race…

For now, I guess I’d just recommend you try to think of ways to relax things and separate project completion from diligence/time management — in terms of vibes if not a 100% mark. Some unsolicited advice from a rando who thinks you’re doing great already :)
