> Creative destruction is brutal math. The capital? Gone. Completely vaporized. But infrastructure isn’t stock certificates. Those fiber optic cables didn’t vanish when Pets.com did.
I read quotes like this and reminded that it is common that people forget money is just a competitive resource we use to outbid each other for _real_ things. Money moves around, it isn't lost or "Completely vaporized", someone receives it at the other side of the transaction. It is still in circulation, it can still be used to outbid people for real things, just by different people.
Also, pets.com still exists, it just forwards to petsmart.com.
Money can be "lost", and "created". In fact, it regularly is by commercial banks; this is the cornerstone of the modern economy. The bank of England wrote a pretty accessible document on money being created and destroyed [1]. For a slightly deeper dive (but equally accessible) check out "Can’t We Just Print More Money?" by Rupal Patel, et al. [2] which describes the different kinds of money.
The 2014 doc was a pretty wild read for me when it came out - it changed my perspective quite a bit.

That's true, but the thing that's lost is the economic/productive capacity that the money was spent on, that could have been used for other (better) purposes.
For example, if I raise $100mn in a frothy market, and spend it on employing 100 Engineers on $1mn/yr salaries for 1 year before ultimately going bankrupt, it's true that the money doesn't disappear, as it was simply transferred from the VCs to the Engineers, but what's spent/consumed is the Engineers' time. Society can never get those 100 person-years back, and the VCs have to write their capital investment to 0.
The other comments are separately true - money is created by bank borrowing and destroyed by loans being repaid or going bad. Periods of speculation often result in increasing leverage (e.g. borrowing to buy stocks/houses), which does result in the destruction of money when it unwinds (as well as damage to bank's balance sheets, which can become problematic when it happens at a large enough scale - see 2008).

But money is an abstraction of wealth, and wealth absolutely can be destroyed, in multiple ways:
1. It can be physically destroyed - if I break a window, that's wealth that is destroyed. That window now needs to be replaced, which costs materials and labor, which could've gone to building something new instead.
2. It can be spent on things that end up not used. If five years from now, those millions of GPUs are no longer in use, we created them for nothing instead of creating more of something people would use.
3. Wealth can be spent on the less important things, rather than the more important things. This is not exactly wealth being destroyed, just built more slowly, because instead of building lots of new wealth (via innovation, say) we're creating less valuable things.
I don't think any of the above are relevant to AI, btw.
What I find so weird always is that well value "vaporized" when prices went down. But what is the term when prices went up? As surely that wealth also respectively came from same place it went when it went down...
"capital" in the economic sense isn't money at all - it's tools, infrastructure, knowledge; from this point of view, you're correct. A bubble bursting on the stock market doesn't destroy capital.
On the other hand, the monetary value of the stock market (and other assets) going up and down does create or destroy "money". From a financial point of view, it's not a zero sum game.
This is incorrect. https://en.wikipedia.org/wiki/Money_creation . A bubble bursting is the inverse process of money creation. Money isn't paper bills or metal coins. It is mostly numbers in a computer.
