I’d say you could render something close in real time. I’m not entirely aware of all techniques used in this film, but seeing what we can render at 60fps in terms of games, I think you could find a way of achieving a Toy Story look at 24fps. You may need a lot of tweaking though, depending on what you use (i was thinking about EEVEE, the Blender ‘real-time’ engine, and I know there are a bunch of settings and workarounds to use to get good results, and i think they may tend to make the render not real-time (like 0.5s, 1s, 2s per frame, so quite fast but not real time)

rules obviously got set up with a specific definition that was understood at the time

Oh boi, having studied law, i can confidently say that using words with no clear definition in laws and trying to apply them is one of the main problematic and debate fuel of judges and lawyers.

And “man/woman” are clearly not words with one specific definition, even in the past (maybe people cared less about the definition, but it does not make it more specific).
