I agree with you to a point. Yes, I think computer literacy is very important, and far too many people think of computers/tablets/phones as magic boxes that show pretty pictures when you click/touch things.

Your Excel example, to me, falls into that category. Learning to use a word processor or spreadsheet application is something that is increasingly necessary in today's world, and I am often surprised by how few people (including, shockingly, many software developers) know how to effectively use them. I just don't feel like taking it all the way to "everyone must learn to program" is a good idea, any more than "everyone must learn to perform open-heart surgery" is.

Based on your comments, I think we actually agree.
