You're right that it's an oversimplification (and frequently an inaccurate and harmful one) to lump people into two groups. You're wrong about the rest though.

You're right that it's an oversimplification (and frequently an inaccurate and harmful one) to lump people into two groups. You're wrong about the rest though. Pretty much everyone uses a computer at some point nowadays, and most people are not intelligent educated professionals, ergo most computer users are not intelligent educated professionals. I would suspect fewer than 1% of Facebook users even know about that incident. Also many people specialize in certain softwares, Excel being a great case in point. I know some accountants who can do things in Excel that baffle me, but still have to call me to set up their Wi-Fi network password for them. They are educated professionals who spend most of their working hours in front of a PC, yet are still not at all sophisticated computer users.
