As someone has to mention and program those robots.
Why couldn't an AI do that?
Someone has to create programs and games, someone has to maintain the infrastructure.
Same question.
Youtube videos and streaming became a job.
This will only work because of the parasocial aspect, and there will probably be strong competition from AI there too.
For every thing you imagine, simply ask yourself - will AI be able to do it better?
So far I haven't heard anything convincing where the answer would be "no".
This whole "giving inputs" argument is 100% leaning on today's technological limitations.
With enough advancements, no input you could ever come up with will be able to compete with the automated ones - even if they are working from some very high level goal, like "make something people want" (to give a slightly exaggerated example).
Nobody's going to pay you to utter the phrase "make something people want" (and it's not competitive as a business either).
