Yet, anyway. For the jfk example, it's not implausible that you could use a nerf type system to generate the 3d scene, then use physics and ballistics models with a CLIP style text interchange to produce statistically verifiable results from natural language queries. These models are too big and unwieldy right now to allow for much finesse, but in 10 or 20 years, that will change. We're barely scratching the surface of Transformers potential, and radical new algorithms or optimizations are likely - a huge amount of human brain power is focused on these things.

All the more impressive that the CIA was able to fake those videos without any computing power ;)

I guess we'll find out when they finally release the records 70 years from now!

Of course plenty of folks have made homegrown versions of Dall-e and GPT-3 and it would be a matter of time before they replicate this a well.
