I wonder the same thing. I suspect the age of the field plays a role. While theoretical computer science is about 200 years old practical computers only exist for 70 years and are widespread for about 40 years. Many professors teaching computer science today couldn't study computer science back in their days because it simply wasn't offered.

This has wide reaching effects, one of the more obvious ones being that 20 year old knowledge seems ancient to most.
