I found some more details about this, for anyone interested. It looks like critics of Tron's visual effects mistakenly thought the computer was generating it all for them, with little human input, when it was actually quite a laborious process.

"Tron’s offices were trailers in the Disney parking lot, recalls Chris Wedge, then an animator for MAGI, who worked on Tron’s light cycle sequences. “[That’s] because the Disney animation department didn’t believe that this was animation,” he says. “They thought it was computers just making effects. They just didn’t understand anything about it.”"

"Tron’s distinctive glowing circuitry was achieved through a technique called backlight animation, which involves making a negative of each frame and hand-painting the glowing areas. There were 75,000 frames to do; more than half a million pieces of artwork."

"Star Wars and Alien both feature 3D wireframe graphics projected on screens. Only a few companies could produce such images, each of which had their own room-sized computer and their own custom-built software. The process was still cumbersome. “We had to figure out how to position and render objects 24 times to make one second of perceived movement on the screen,” says Bill Kroyer, Tron’s head of computer animation. Tron’s animators had to map out the CGI scenes on graph paper, then calculate the coordinates and angles for each element in each frame."

I no longer remember the details but I certainly didn't get the impression that "human input" vs "no human input" was the actualy criterion.

And this line to me is meaningless unless we have specific definitions of what the Christ Wedge meant by "animation" and "just effects"

I'm not really sure what you're trying to say, sorry. What else do you think he might have meant?
