Steven was a developer on NeXT, working on Mathematica when I was there. He's a very smart mathematician but damn he had a volatile personality. The match between his software and our platform was perfect because power of UNIX, beautiful interface, but we did not sell enough machines for him to make money and it drove him crazy. I'm so happy to see him emerge as he's done.
He's right about those glasses. It isn't pseudoscience like it sounds. I have a pair and here is Caitlyn in hers. She absolutely can ride no spinny rides or roller coasters unless she's wearing them, and then no problem.
