I do feel kinda bad for people. There's very few jobs left where you don't interact with a computer in some form or another, and the reality is that it's not for everyone. Of course most people can benefit from using these "tools" but since they're always upgrading, there keeps being something new to learn.
Personally, I love technology and playing around with new tech. However, if I'm great at sales or a lawyer or something, that's where I add value, not in knowing how a computer works. So I can see how people get frustrated with it.
In the end it boils down to, pretty much everyone needs IT, but IT doesn't need everyone. Think about it, when was the last time you worked at a company where an employee didn't have a computer or need a computer for some task that they do?
