Thank you for a legit insight about video. My guess is changing to micropayments, like you should pay 0.01$ or less to be able to write one comment, also the price could be higher for participating in controversial topics.
Internet should be open (for authoring, for participating). Paywalls destroy everything.
People should invest in anti-gen-AI algorithms. And make AI filters new infrastructures of Internet.
I am sure that even sub 0.01$ payments will effectively filter 90% of the spammers.
If it is too high it will significantly prevent participation from humans, because most of the content sent by real humans on social media is not much different from spam...
