I think there's going to be an element of this, but how pervasive will it be?
A plurality of that plurality has a higher education degree from an institution that isn't world famous - including myself. I don't feel at all threatened by self taught people, honestly I was not a great student and consider myself partially self taught anyway.
How pervasive it is depends on how scare resources are. From my experience as resources get scarce humans group up together by a one or more of the common properties they share.
Race, religion, county of origin, urban or rural, sexuality, union or scab, favorite sports team, etc
I don't see why educational attainment is any different. The only part that is missing in the software industry is a scarcity of resources and the shift described in the grandparent comment and those behaviors will happen at scale.
