It's a tool. The people you see using it now are the early adopters and the hustlers.
You'll see the young artists picking it up soon. I know several awards winning VFX industry folks that love playing with it, but they're afraid to tell their colleagues.
Joel Haver's use of EbSynth [1] is probably an indication of how this will be used successfully at first. Strong sketch comedy and improv performers using AI to elevate their visual presentation. From there it'll grow.
Obviously. Because if it was trained on previous VFX artist work and now puts VFX artists out of work it's a bit icky to talk about with fellow artists. But also because if they use it then more likely you are out first. Eventually they are out too, when studios/platforms/owners realize they can just use the tool directy and skip the middleman, but until then it's a charade where everyone pretends it's not happening and all is fine while house burns down.
