My understanding is that it was more the 9000 bank failures effectively created a credit crunch. Like if a bank closes and there's no replacement, then most small business were unable to get loans. Farmers who couldn't afford to plant new crops, factories can't improve equipment, inventory get's squeezed across the supply chain, ect. Exports were about 5% of GDP, suggesting that maybe tarrifs may have been the trigger but weren't the primary cause of the depression.

But what if the DJ convinces his audience to invest in a much larger and more expensive night club at an extraordinary premium. Then it might make sense to buy the original night club just to protect the DJ’s scheme.

My math is that Musk’s twitter activity very reasonably increased Tesla’s market cap by more than 5% which is what he is offering to pay.

I mean, 90% of large cap investors have underperformed the sp500. It's not about optimal returns, it's about diversification and portfolio risk. The Saudi's want some of their money in things that aren't correlated with oil, and pretty much everything in the physical word is. Technology is one of the few things that may even be inversely correlated.

I think you can decompose a calculus course into three key components; principle/concepts, proofs, and procedurally solvable math problems.

All three have value but clearly the math problem aspect of it has depreciated in value due to calculators, wolfram alpha, etc yet it tends to remain the focus of many math curriculums. Calculus by its nature is more computationally intensive, meaning that it has experienced the greatest decline. If you really think about it, that curriculum was designed for an era when we called human "computers". There is probably opportunity to make calculus a more broadly valuable class by deemphasizing the mechanics and focusing on the principles and proofs.

This is wonderful. I’m going to see if there is anything I can build for this.

I think it could be Nobel Prize worthy. Protein’s structure often determines its effect as a catalyst. So to map the DNA to the 2nd order outcomes seems like it could be the missing ingredient to controlling the properties of cells.

Personally I’m hoping that someone smarter than me figures out how to displace existing catalysts like platinum and palladium. Seems like it could be a pretty penny and some positive environmental impact to boot.

It seems to me that there are two ways to learn well. One is to have a carefully curated curriculum and the other is to have enough experience to parse the world by yourself. In humans we might describe these as knowledge/education and wisdom. I see data preparation as improved knowledge transfer and more training data as the path to wisdom.

Wisdom is usually heavily discounted by smart young people so I expect engineers will double down on better data prep than better data acquisition. Also which looks better on a resume?

I’d say that the first premise is objectively false. I think it’s much simpler. The volatility of asset has correlated narratives of hope and fear in the mind of the asset holder. These in turn produce a dopamine response, akin to mechanisms of a gambling addiction
