Corn is heavily subsidized,also has (in the US) federally prvided insurance programs against plunging prices, has paid uselessness(ethanol). Despite all of this corn has caused massive agriculture bankruptcy/takeover when it has failed anyway.
So it's more "what's special about corn". It is also fairly hilarious to claim the parent is denying basic economics and then bring up corn as an example of having successfully managed economics. If the scales were not being thumbed, and "basic economics" were in play, corn would be in very very bad shape.
In the case of DRAM, there is an incredibly long history of these gloom/glut cycles, and they have stayed roughly the same timeframes (~3 years) since the 1990's.
Almost all the ones who have survived this long are either in the same kind of boat as corn - protected in various forms from the downside - or don't increase production and get caught out until they are absoultely forced.
The very temporarily increased profit is not worth going bankrupt for - they make more money long term by being very cautious and know this.
There are a near infinite number of economic studies you could look at (and several sibling comments cite some) - DRAM manufactuers don't chase the price and probably couldn't anymore if they want to.
None of this denies basic economic theory, of course, since economic theory is not exactly "rigorous", even to the degree it could be (IE even the parts that are pure analysis of data rarely reproduce!).
I don't think that anything you said is wrong but I also don't think that memory consumption is going back to the old baseline... well, ever.
Memory is just too useful now that you can use it to drive cars and write code.
The problem is that is speculation and the market barriers are currently too high for losing business to be a threat. The two outcomes are (1) you overbuild, you end being wrong, you go bankrupt and lose everything or (2) you are right, but since you didn't overbuild, you lost out on some revenue, but demand still exists 3 years later and you didn't lose everything.
In any other business choosing (2) would mean someone else swoops in and steals all your business. It doesn't look like this is at all possible for memory fabs.
Well, the Chinese manufacturers are certainly coming, though CXMT seems to be being careful not to rock the boat, at least yet https://www.tomshardware.com/pc-components/dram/chinese-cxmt... .
It makes sense, CXMT takes as much profit as possible, then use that money to build more capacity, ultimately becoming one of the biggest competitor (only?) to the cartel.
As of Q1 2026: 90% market share for the Big Three, 8% CXMT, 2% everyone else. And CXMT was only 3% Q1 2025.
People are happy to play with AI when the tech companies are burning hundreds of billions of dollars to subsidize it. It remains to be seen who is actually willing to pay for it at the prices required to recoup those insane investments.
Which directly leads to the next big development: all the big players are investing in silicon with "baked-in" models, like [0,1]. Turns out you don't need an expensive general-purpose GPU with heaps of RAM to contain a model when you can make a custom ASIC around one specific model! Why spend a fortune on DRAM / HBM when all you need is some finetuning parameters which are easily stored in on-die SRAM?
