I am looking up the stuff you’re talking about, haven’t formed an opinion yet, but my current thinking is… nobody really understands economics, not in a predictive sense, there just isn’t a good theory that neatly accounts for everything, it might not even be possible. And when you throw AI into the mix I think things get weirder still. With very heavy automation… even if a small cadre if engineers is needed to main the system, the capitalist could potentially own literally an entire economy, no need to trade with anyone or think in terms of money, they desire something and the army of robots does its best to deliver it. A theory that can’t analyze such a situation likewise will miss something about whatever situations like between now and whenever that becomes possible. The point is, whether you find such things plausible or not, the capability gains of AI over the past 10 years have astounded even the craziest of optimists, there’s no sign of slowing down. If research came to a screaming halt, implausible, we haven’t even reckoned with what’s already been created.
