Well, you are assuming there is a central benevolent dictator who can compute "Value" more accurately than millions of people collectively voting with their wallets.
If AGI is actually attainable, then, sure, planned economies will be more performant than market economies, especially for high value industrial captal equipment. No need for Gosplan to decide on your candy bars and craft breweries.
A market economy is a distributed compute engine. The main reason why planned economies do worse historically is because the amount of compute needed to actually account for everything centrally is so immense (and thus costly), the implementers necessarily have to adopt some kind of simplified model, and then you get divergence between what the plan says and what's actually happening.
It's not a given that this will remain true forever, although I don't think it's tied to AGI. One could argue that AGI push is the trigger for a massive increase in compute capacity and corresponding decrease in price that might make this kind of thing viable, but that's just wishful thinking, not a fact.
That sounds like the finance bro version of mystical woo. There's nothing special about it. There must be doctors who say diagnosis is an art form. But AI will still out perform the diagnosis.
AI can calculate stuff that can be measured and calculated.
But investing (in stocks or otherwise) is not that. Investing is about the phychology of the people (all other investors). If investors as a whole make stupid decisions, the market movements make their decisions correct (like the incredibly stupid drop in Nvidia's stock due to release of Deepseek). AI can be more objective and better at calculating facts, but it doesn't matter if the market is driven by emotions and people.
It's implicit. Amazon has billions of dollars because customers freely handed over the money. We know they found the service valuable because they wouldn't have done so otherwise.
The poster is suggesting there is some _true_ value separate from what these customers who know their own situations best think. That they are secretly being fleeced and a central planner will somehow better allocate the resources.
"The ultra-wealthy should have less power" != "We should implement a five-year plan for our command economy as thought up by glorious and correct Party."
If I run around town smashing windows with a rock, GDP goes up. Computing value more accurately than financial markets is not difficult: the bar is on the floor.
Breaking windows DOES increase GDP, just like the parent said. The argument ( https://en.wikipedia.org/wiki/Parable_of_the_broken_window ) only argues that not all GDP increase is good, because of waste of resources, because of the opportunity cost. That's why measuring success only by GDP is a bad idea.
