To be honest, it's kind of already happening. It's long been a trend for certain people to use cartoon representations of themselves that look a lot younger/more conventionally attractive than they may be in 'real life', and there are quite a few YouTubers and Twitch streamers using either animated portraits of themselves or fictional characters as their avatars. The big difference in future will be that more people will be using avatars that look more like actual people/deaged photographs of themselves instead.
