I didn't really see much specific stuff here, to be honest. There was some program that you could use sliders to figure the best life insurance policy ... I mean, ok ... that's great ... What's the big deal again? What are some specific examples. There's all this "wah schools only teach calculation." Well, what specifically are they teaching that is bad and what specifically should they teach that is better? So, are we saying, no reason for a student to know how to take a derivative, they should know how to turn the knobs on some program to figure out the best fuel efficiency of some device in some really neat simulator? The example about limits ... ok yeah that's cool but if you aren't actually teach them how to "calculate" (is the word "calculate" used as a boogey man?), how is that you are not doing anything other than teaching "math appreciation?"
