Excellent response with plenty of empathy for your folks. I remember trying to teach my mom the fundamentals of programming decades ago as a teen and feeling nothing but frustration with her inability to comprehend even simple concepts.
"You're looking at it rather narrow-mindedly ..." That's typical for Anonymous Coward, unfortunately. While he (or she) sometimes has informative, insightful posts, more often than not, he's a mean-spirited ass. I guess I should cut him some slack, though; he's extraordinarily prolific here on Slashdot, and has been for years. Every article has dozens if not hundreds of (mostly useless) Anonymous Coward quips, and he often argues with himself. In the end, I guess he's just a lonely savant; sheltered and disabled and living a life in solitude except for the meager relief derived from Slashdot.
