Cars are also very prevalent, and surprisingly most of the people in my mandatory auto class in high school didn't give a shit. Just like the compulsory computing class they had to take.

How much programming knowledge is required to use a smartphone? This is the thing nobody in the software literacy camp seems to acknowledge: tightly integrated devices with walled-garden software ecosystems are the industry trend. Yes, some people in maths-heavy fields will need computing more and more: financial analysts, engineers. These people are already taking intro computing classes at the undergrad level (engineering computation is a prereq for mech eng where I study). But the average person with an iPhone isn't going to put up a hundred extra dollars to write an iPhone app to fix their own problems.

I think the longer you've been out of high school, especially if you're working or studying in an insular environment, you forget just how broad 'everybody' is. I know lots of people from my school who are now bricklayers, or auto mechanics, or grocery store clerks. Understanding a while loop has not substantially improved their quality of life, even though we had a kickass comp sci teacher. It's just not as relevant in daily life as we want to believe.
