Im not sure it's completely true, it feels like throwing the baby with the bath water. Yes you get rid of YouTube, Reddit and other social media infested in ai generated content but there is value on those website. I looked at YouTube yesterday on how to do placoplâtre, just today I read interesting article on sh.itjust.works and sometime ago had interesting conversation here, and so on. If tomorrow I'm viewing computer generated article, talking with bots and viewing bot generated video i might as well quit internet completely and live like in the 90's. It would be a setback, not improvement.
it's saying people will stop using free social media like twitter, facebook, youtube, etc.. because of spammy bot generated content.
Less people, less reason for youtuber to upload helpfull video or people providing educative content on other platform.
