Yes, and all those appliances are built by elves. Certainly not by people who were in high school years ago. And the future of those "appliances" certainly won't be built and coded by people who are in high school now.
Besides, it's not like the next generation of code hackers won't be there if they don't learn it in American high schools. They're learning it in Korean, Chinese, Indian and Japanese (and even Russian) high schools.
Wow what a long list of idiotic assumptions built into bad sarcasm all having no basis in the passage quoted. Just because somebody didn’t learn Linux in high school doesn’t mean they’ll never learn it or can’t program it. I’m in a generations programmers who didn’t learn Linux in high school, BECAUSE THEY ALL GRADUATED IN THE 80S, and they seem to be programming just fine, many are even making apps for Linux.
