Predictive processing is absolutely not garbage. The dish of neurons that was trained to play Pong was trained using a method that was directly based on the principles of predictive processing. Also I don't think there's really any competitor for the niche predictive processing is filling, and for closing the gap between neuroscience and psychology.
the most sane interpretation is just evolving wavefunctions according to schrödinger's equation with no extra bells or whistles. collapse is just decoherence.
Land valuation is necessary to implement a land value tax (not to be confused with property tax) which is the main thing Georgists advocate for. Georgists and YIMBYs have an affinity for one another since land value tax disincentives speculation and incentivizes building.
Prediction markets were initially proposed to provide a social good, the idea being that the ratio of the current price of a share in a prediction market to the value of that share if the market resolves to "yes" is how likely the market thinks the market is to resolve "yes" as a probability. The social good is that you could use this to predict the future.
