I also watched that doc a week ago, and loved that pioneering spirit from Dykstra and the other heroes of my youth. In the next 5-10 years, I think that the growth of AI in VFX will bring some of that back. In fact, that's happening right now, across the world, as every VFX house seems to have some sort of AI skunkworks in place; techniques that are not ready for prime-time, as many applications of CGI weren't throughout the eighties, but who time is yet to come.
