I'm with you. I feel like a large portion of today's PC gamers are just console gamers who happened in to money one day and picked up an expensive rig. I don't expect everyone to know everything out of the gate, but I'm amazed at people's inability to learn.
Interestingly, people who came before the technological age of the past 20 years or so couldn't use technology, so developers of hardware and software made things progressively more and more accessible. The problem this has created is that the new generation of software and hardware users don't even know the basics, since they've been raised on the "super accessible" version of technology. Basically, they ONLY know how to operate in a spoon-fed world.
If you show a kid how to add with calculator before teaching him how to add on paper, he'll never be able to understand how to add on paper. He'll never understand why it works, only that it does.
