  • Depends on how you take it. When you say anyone who doesn’t have a neurological disorder can do something it puts a negative light on people who haven’t done it. Not being multilingual is a common negative statement about Americans, for example, always comparing them with Europeans. But most Americans don’t live close to multiple places where different languages are prevalent, as in Europe, so their only reason to learn other languages is purely academic. Similar to the average person’s motivation to learn calculus. I think I framed it pretty realistically - certainly with more brevity.







  • Back in the 1990s I did a thought experiment using 1990s industrial cost figures and production volumes I found online. Turned out Americans could save the Amazon rainforest by cutting our beef consumption by 10%. I don’t have the math on hand but the gist was that if demand for beef in America dropped 10%, so would demand for cattle feed, which was mostly corn. Reducing corn production by that much and devoting the land to hemp cultivation (which would work) would produce enough hemp fiber to replace all the wood pulp being imported from Brazil to make paper. At that time most trees being logged in the Amazon region were being pulped and exported to the US. So boom, demand for Amazon pulp logs drops to zero, rainforest saved!

    Admittedly this was simplistic and did not account for pulp producers selling to other countries that may have been competing with the US to buy the pulp. But they would have to compete with whatever other pulp sources those customers already had. Anyway, just the fact that the numbers worked out so well helped me understand how a trend in one area can affect seemingly unrelated areas. Like, I dunno, people buy fewer Barbies and the price of air conditioners goes down. I’m sure some people make a lot of money by figuring out stuff like that.


  • Insightful. I think what happened with tuition was that universities were actually undercharging until around 1980, when they realized they could charge a lot more and people would still pay it, so they did. In America there’s a prevailing mindset that the economy boomers grew up in was normal, and today’s economy is stunted. The economy of the 1950s and 60s was actually an anomalous boom, like a bumper crop. Today’s economy is what it would have been decades ago if the business world had risked charging higher prices and paying lower wages back then, instead of waiting for an excuse like COVID. Kind of a harsh realization.





  • Great interview! The whole proof-of-work approach is fascinating, and reminds me of a very old email concept he mentions in passing, where an email server would only accept a msg if the sender agreed to pay like a dollar. Then the user would accept the msg, which would refund the dollar. So this would end up costing legitimate senders nothing but would require spammers to front way too much money to make email spamming affordable. In his version the sender must do a processor-intensive computation, which is fine at the volume legitimate senders use but prohibitive for spammers.
