Not sure about de-evolution (devolution is the word I think), just a change in how people and brains work - but you could already see this happening the past few decades. I can't read a technical book or documentation end to end ever since google results came up with specific answers within seconds.

A technical book can be so relaxing (unless e.g. too highly technical... think quantum mechanics). Imagine 50k words on an interesting tech topic without a context switch!
