Prediction markets have pretty much obviated the need for these things. Rather than rely on "was that really a hot take?" you have a market system that rewards those with accurate hot takes. The massive fees and lock-up period discourage low-return bets.
FWIW Polymarket (which is one of the big markets) has no lock-up period and, for now while they're burning VC coins, no fees. Otherwise agree with your point though.
As opposed to the current world of brigading social media threads to make consensus look like it goes your way and then getting journalists scraping by on covering clickbait to cover your brigading as fact?
