Oh joy. Added complexity...
My wife half-expects that at some point the sum total of IT/networking/power distribution will become so complex and (for want of another term) balkanised into specialisms, that it essentially becomes impossible for humanity as a whole to maintain it, and then something will break and we'll be back to heating with wood and communicating with pen an ink (or maybe IT jobs will become more critical to society than doctors/nurses and we'll all die from treatable diseases??).
When you add in obsolescence, shortening product-lifecycles and lost/outdated skill-sets (is anyone anywhere employed as a thermionic valve designer any more? How many people can read amd64 assembler compared to the numbers who could write 6502 or Z80 30 years ago?) then I tend to agree with her.
