I think the most interesting thing about making AI to serve human interests is that ultimately the system of AI (foundation model + infrastructure + energy) should resemble a human system.
Zero real rate of return. If bonds have a negative real rate of return and stocks have a RISK-ADJUSTED negative real rate of return, then gold or more generally commodities are a better option.
BTC Ledger =/= BTC consensus. If the protocol can be made pure proof of stake while maintaining the same availability and security guarantees this is no longer an issue. However, this is against the best interest of miners.
Is it fair if people can be restricted from competing in the property markets by people who faced no such restrictions themselves when acquiring that land capital. Zoning licensing, etc.
The elephant in the room is that for most people the majority of their net worth is tied up in housing (property) and as interest rates drop the nominal value of this property increases way faster than the nominal wages of labor. This property can then be used to create information insensitive debt that ignores any notion of liquidity at an artificially higher nominal value. This debt is then used to pay wage-labor who increasingly cannot acquire property themselves. At the end of the day, only real property is wealth (land, ip rights, equity, collectibles, and machinery) and labor is denied the opportunity to earn a larger share of property themselves. Any solution is politically difficult.
