It's not that they're bad at what they do with computers. It's just what they do with computers is not worth doing.
It seems that this happened somewhat recently.
Suffice it to say - just like you felt when you were younger - most thoughts that boil down to "damn kids these days!" are almost certainly not true.
Of course it's silly because of the global productivity gains. And it may just be my innate misanthropy which made me a nerd when I was younger now manifesting in this new form.
I'm already an old man annoyed by people my age and annoyed by older people. But truth is, I'm annoyed by most non technical people.
PS: I like discussing technics with people from non tech fields though, luthiers, masons, cooks etc...
