I didn't go to one, but I'm entirely self-taught. I'd seriously advocate for you to open your mind a bit.

I once had a boss that had a very similar attitude to what you're talking about here, and I left the position pretty quickly. And not once have I felt constrained by my lack of degree- if anything, the self-learning put me in a place where I more quickly learn new technologies because I'm more active in starting side projects using them.

I understand that one's school is a huge impact on their experience, but don't let it become an implicit endorsement.
