It's kinda the rule for programmes too.
The ones that went to a small liberal arts school you've never heard of programming as their second career are usually more effective to work with then the Stanford/MIT crowd.
The problems start I think, when you have an expectation that your collaborators are somehow either superhuman or subhuman and not peers.
Humility and mutual respect gets things done.
I've worked with some younger designers who couldn't even put together a consistent click-dummy once the client wanted to see flows outside the happy path. To be fair, all they really had to go on was their education and Figma's panels.
I stopped looking at the educational background years ago in a fear that it would influence my bias either way. We shouldn't base someone's suitability at 40 upon what opportunities they were afforded at 17.
I do have a somewhat prestigious pedigree btw. I removed it from my resume around 2010 and never looked back
