I wasn't saying anything of the sort. I'm just pointing out that the complexity and writing speed of one's longhand writing system is less important in computer science than, say, art history, or psychology.
In case you have missed it, there seems to be an undercurrent in this thread that implies that one has to give up cursive in order to teach computer science... Thus my comment that you quoted.
Computer science is a field that (generally) doesn't require much writing. Are you sure that's a good example?
I also think there's an aspect to this "undercurrent" that you're missing. One doesn't have to give up cursive to learn keyboarding (in fact, experience tells me that schools do both), but if one were to give up the time spent learning cursive and leave time for keyboarding, there might be extra time to learn other things, or to get very good at typing. There's only so much time in a school day.
