Thoreau, who is a physics professor in real life, notes:
this is going to make me sound even more evil, but screw it: Despite what the article says about the problems with “separate but equal”, when it comes to educational technology there may just be cases where we have to accept it. A powerful case can be made for the use of interactive animated simulations when teaching science, e.g. the user gives the mass and length and starting angle of the double pendulum and then the computer shows its chaotic motion. To the extent that a picture is worth a thousand words, and a picture that changes when you change the parameters is worth even more words, it’s going to be close to impossible to produce anything based on text or audio that produces the same pedagogical benefits.Anyone familiar with American pop culture from the past fifty years or so has seen movies or TV shows featuring cartoony villains who threaten to kill the person they just kidnapped, or destroy the priceless piece of artwork they just stole; the villain's justification is "If I can't have this, nobody can! Bwa ha ha!"
I don't think today's equality fundamentalists understand that "If I can't have it, nobody can" is an expression of psychopathic selfishness, not a noble ideal society should strive to achieve.
