Educators come up to me all the time with concerns that students can’t word process on an iPad — I have pretty much zero concern about this. Kids can write papers using Swype on a smartphone with a cracked glass. Just because old people can’t type on digitized keyboards doesn’t mean kids can’t

I’m not concerned that kids can’t learn to write English on an iPad, I’m concerned they can’t learn to write Python.
