> I expect we'll see something like VTubers on a mass scale. Companies creating their own virtual people - where they control the IP - and putting all their efforts behind promoting them instead of humans

I'm reminded of the "failure" of Kizuna AI; the fully corporate vtuber whose human side is just a puppet operator who can be swapped, turns out not to be very appealing to audiences. The modern approach where a model is exactly synonymous with the person playing it, as an authentic human improvising, appeals more. The IP doesn't persist beyond the contract of that person with the company, and certainly can't be swapped with someone else. But in some cases the actor or actress has successfully maintained their career and fanbase under a different name following a fallout with their managers.

This is far beyond the turing test, and I don't think we're really ready for what happens with human-indistinguishable automated corporately owned doppelgangers.
