It’s an interesting article, I couldn’t help but think of how “Pirate Speak” really comes from Robert Newton’s acting in a famous Disney movie. So while it predates big tech’s debasement of culture it’s still a “top down” artifact, in a way. I guess you could say it came from a creative decision of an artist (Newton adapting his native accent) and initially caught on for good fun rather than for profit. So far less cynical than the radioactive shit getting pumped out now, if for no other reason than in the 1950s Disney hadn’t figured that shit out yet.
Back in the day TCL was used in a few places in Pixar’s Renderman renderer (called PRMan), and in its connection to Maya. You could write little TCL scripts within the Renderman Artist Tools (RAT) that would be evaluated during scene export. I think this still exists in some form inside Tractor, which is their renderfarm management software.
It’s been a long time since I used prman but generally Python has replaced everything as the “glue” language, which honestly makes things a lot easier. VFX and game dev used to have a hundred different scripting languages rolling around.
