Back in the 90s, IT people were magicians. Now they are plumbers. So much of today's infrastructure relies 100% on IT support -- people can't just write it down, or file it manually. IT folk are in charge of a giant, critical piece of the everyday workload. But expectations are that it will just work, and that things will keep moving forward as new technologies arise. Back in the day, IT could handle an entire 500 person company with 2 or 3 people -- it was all printers and email. Now it's files and databases and remote access and web apps and mobile apps and security and policies.
The IT folk who are more stressed are the ones who haven't staffed up. I've no comment on the younger set...I'll defer to Socrates as people have suggested.
