Yeah, maybe for some purposes. In business, people sometimes pay for stock images but often don't have the expertise or patience to really spend a lot of time coaching a video into fruition. Maybe for advertising or other contexts where more effort is worth it (not just powerpoints), but it feels like a slim audience.
With tools like Apple Intelligence and its genmoji (emoji generation) and playground (general diffusion image generation) I expect it to also take on some of the current entertainment and social use-cases of stickers and GIFs.
But that’s probably something you don’t pay for directly, instead paying for e.g. a phone that has those features.
