This is already happening. We just call them "influencers" or "YouTubers". These are still technically real people, but they're real people playing a sanitized character while appearing/claiming some degree of authenticity. They are actual photographed humans, but often wildly digitally retouched to be more beautiful than any actual person.
And people increasingly are replacing real relationships with parasocial relationships with these complete strangers. It's understandable: like junk food, it satisfies an immediate craving with no real effort on the part of the consumer. But long-term, it is deeply unhealthy.
