This is such an uncharitable take of your peers.
The issue is not pedigree - it’s that many folks have an incurious mind.
I certainly know many folks with a CS degree that are incurious and frankly terrible engineers. I also know bootcampers that are extremely curious, have a lifelong-learner attitude, and are subsequently great engineers.
There’s nothing special taught in the vaunted halls of a CS undergrad that can’t be trivially learned off YouTube.
I agree with your first couple of sentences. But the YouTube bit is dangerous misinformation. You cannot match any credible university education by watching YouTube.
