Or, you know, not. It's a settled thing, and has been for a long time.
I'm too old to have been part of the TI cohort, but I had one of the early graphing calculators in high school (1987 or so), from Casio, and let me tell you having the ability to quickly graph a function is actually SUPER USEFUL, especially in an experimental/learning environment.
So maybe stop whining that "millions of kids" elsewhere or in the past didn't have one, because it's completely irrelevant.
