Once during COVID, I was at a virtual conference; a PhD student was presenting and was like, "it's 3am here and I'm really tired, so, here's what I'm going to do. I'll play a prerecorded video of me giving me talk, and if you have any questions, I'll pause it and answer".

Fun fact: when you get a mortgage against your house, the bank orders an appraiser to estimate how much the house is worth, since regulators like the loan to be less than 80% of the house value so the loan is safe. The appraisal values have a very curious distribution.

Personally, I read a bunch of classics in high register in college. I guess it was fun. I recently ChatGPT'd Aristotle into readable English, finished it around 5x as fast as a translation, and felt I got the main gist of things. idk does the pain incurred actually teach much?.

Probably the silliest anti-blockchain argument, IMO, is that it doesn't have credit card purchase protection, chargebacks, etc. You are literally forcing everyone to pay 2% of _everything they buy with a credit card_ for purchase protection! 2%!!!.

A lot of so-called "burnouts" of promising kids in college are really very happy situations. People was pushed by family/cultural circumstances to grind more than they would like to. Given freedom, they choose simply to enjoy the short time we have here on earth how they want.

The plots above are not mine, but @EXjiang and I wrote a model of how appraisers bias prices upwards, and how this affects mortgage credit provision in more and less liquid housing markets, in this paper!.

I'm advising the UChicago blockchain club now, so I know a bunch of very smart UChicago undergrads looking for web3 jobs. Devs and nontechnical positions. Anyone hiring? LMK and I'll send you a bunch of resumes.

IMO a major flaw of standardized testing-based education is that it doesn't teach decision-making under risk. Poker does; sports does; etc. A student brought up in a test-based system might think of life as basically a series of probability-near-1 grindable challenges.

A piece of advice sometimes given to econ/finance PhD students is to read the WSJ, FT, newspapers, etc. for research ideas. I think a sometimes better alternative is, whatever field you're working in, there's probably a regulator: go to their website and read stuff they put out.
