Of course it’s possible I’m wrong. But if we make any sort of projection based on current developments, it would certainly seem that live-streaming AI indistinguishable from a human being is vastly beyond the capabilities of anything out today, and given current expenses and development times, seems to be at least a few decades in the future. To me that is an optimistic assumption, especially assuming that live presence or video quality will continue to improve as well (making it harder to fake.)

If you have a projection that says otherwise, I’d be glad to hear it. But if you don’t, then this idea is merely science fiction.

Making predictions about the future that are based on current accelerating developments are how you get people in the 1930s predicting flying cars by 2000.

You imply that the technological development will stop, but that's not what happened to flying cars - they do and could exist. Since the 1930s the technology didn't stop developing - aircraft went jet powered, supersonic, to the edge of space, huge, light, heavy, more efficient, more affordable, safer; cars went faster, more reliable, safer, more efficient, bigger, smaller, more capable, self driving; fuel got more pure, engines got more power per kilogram, computer aided design and modelling of airflow and stress patterns was developed, stronger lighter materials were developed; flying cars have been built:

The Terrafugia Transition 'roadable aircraft' from 2009: https://en.wikipedia.org/wiki/Terrafugia_Transition

Moller SkyCar, of course, which never got to free flight, but was built and could fly.

The problems are regulatory, cost, safety, massive amounts of human skill needed, the infrastructure needed, the lack of demand, etc. A Cessna 182 weighs <900 Kg, a Toyota Corolla weighs >1400 Kg and has no wings, no tail. But if we collectively wanted VTOL flying cars enough to put a SpaceX level of talent and money at them, and were willing to pay more, work harder, for less comfort and more maintenance, we could have them. Bit like Hyperloop; a low-pressure tunnel with carriages rushing through it is not impossible, but it's got more failure modes, more cost, more design difficulties and almost no benefits over high speed train and maglev.

For many people current AI created videos are already confused for real videos and vice versa.

When you follow up on technology by browsing HN, and see the latest advancements, its easier to see or hear the differences, because you know at what to look.

If I see on tv some badly encoded video, especially in fog or water surfaces, it immediately stands out, because I was working with video decoding during the time it was of much less quality. Most people will not notice.
