What Can We Learn From the Chinese Housing Bubble?

Anyone can use our theory, which has been confirmed by events in foreign real estate markets, when determining whether to buy a home
Bubbles are created by speculators who don’t care about an asset’s income because they expect the price to keep rising. For most buyers, income is what counts.

Might Now Be a Good Time to Buy a House?

I asked ChatGPT, Gemini, and Claude and they confidently spewed bucketloads of well-written but barely relevant prose. There is a better way to find out
All real estate is local but, despite bubbles, it is generally better to buy than rent.

UFOs and Crop Circles: Believe It — or Don’t

Alleged evidence of extraterrestrial visits often evolves from local news headlines into a game, an art, and an industry
Even when the pranksters who create the often elaborate crop circles are identified, "croppies" insist that only ET could have done it.

Colleges and Universities: Still on a Road to Nowhere

One cost-saving proposal has been to eliminate courses with ten or fewer students, irrespective of what the course is teaching
Significantly, no administrators who were contacted recommended reducing schools’ budget woes by reducing the number of administrators.

Computer Intelligence Versus Human Intelligence

Professor Joseph Weizenbaum created a chatbot he named ELIZA that conversed with users the way a psychotherapist might
Even though the users knew they were interacting with a computer, many were convinced that the program had human-like intelligence and emotions and they happily shared their deepest feelings and most closely held secrets.

The Core Problem with Large Language Models

LLMs are inherently unreliable, which means that failures are not incidental, easily fixable glitches
The data deluge exponentially increases the number of coincidental, useless statistical patterns — so the probability of useful patterns approaches zero.

Is OpenAI Approaching the Valley of Death?

Overpromising is still a big problem; in any event, the fate of Netscape looms
OpenAI needs to show that ChatGPT is more than just the first publicly available LLM. It has not done that and maybe never will.

Home Ownership: Madness Over 30-Year Mortgages

It is tempting to put borrowing and investment decisions in separate mental buckets, but they are intimately related
When considering a mortgage, the correct comparison is not total payments but the return on the borrowed money versus the loan’s annual percentage rate.

Illusions: No, Large Language Models Do Not Understand

A recent New Yorker article is mistaken about this. For one thing, the LLMs have trouble distinguishing between causation and mere correlation
A real-world example of such struggles is the poor performance, in general, of AI-powered mutual funds.
