The really, really, really fun in this strip is how the joke is aimed a little to close to home for a good part of the readers, if the comment section has to be used as reference.
The leap is not so often in the basic structures and metodologies, standards, etc, but in the little changes in uses and acception in general society: Remember when Microsoft almost lost the train because they though internet won't go anywhere? What about the smartphones thinguies, and their popularization diametrally combined whit this social networking stuff? May I have a nickel for every old school that's ranting about the cloud computing concept just because is against his school of thought (and not because other, maybe a lil more valid, issues...)
Oh, and modems where a headache way before they actually hit you with 'em =)
Everything is still just a turing machine. Well, a finite state machine, if you want to get pedantic. I stick with lambda calculus, and avoid those new fangled programming languages like perl and cobol, and I get along just fine thanks. It's algorithms, architectures, and heuristics that matter, not the coding language... and good system design is only learned through many years of hard experience.
