One possible future is going back to a medium with higher cost of publication. Books. Handchiseled stone tablets. Offering information costs something.
If you didn't submit a proof of work of N or greater difficulty the email would be thrown out.
Honestly I’ve switched to books and papers a few years ago and it has been fantastic. 2 hours of reading a half decent book or paper outweighs a week of reading the best blogposts, twitter threads, or YouTube videos.
Then once you have a hook into your topic, it usually cites 30+ other papers that may be worth reading. You will never run out.
The grifters are all over that already. No AI necessary to generate and publish drivel.
See “Contrepreneurs: The Mikkelsen Twins”¹ by Dan Olson² for an informative and entertaining documentary on the matter.
