An interesting implication of this is that AI inference and training has a path to a ~3x hardware cost reduction (and maybe ~2x total cost reduction) without any technical innovation whatsoever, we just need to wait for dram supply to meet demand (either by manufacturing scaling or just waiting for the current rate of manufacturing to fill the demand spike).
Earlier quoted context omitted.
Supply will not meet demand. What incentive do the handful of dram manufacturers have to end the party? This is what happens when legal monopolies finally win control. Dont't worry. The patents will expire in a few decades. Our grandkids will see DDR5 get cheap again. The system functions as intended.
I have fairly simplistic view of the economics involved here. Could you explain why the ability to sell more chips wouldn't be sufficient enough incentive to increase supply?
If it was just variable costs and new capacity was available today they’d do it. But there are substantial fixed costs and delays to increasing capacity, and that uncertainty makes it risky.
Everything I read seems to suggest that RAM capacity is going to grow at 20-25% a year, which just doesn't seem good enough. Even in consumer use cases, phones and laptops would benefit greatly by double the amount of RAM. And then obviously, the AI need is gigantic. I don't see it going away. I mean, it may not grow as fast as now, but I don't see it growing away either. I get why the memory makers do not want to ba…
I don't actually know what the rate of growth before October was, I'm sure someone round here will though.

> a path to a ~3x hardware cost reduction Really? How long do we have to wait until that ... cost reduction hits us?
Safe to say at least a year or two. It'd be shocking if it took a decade.

The memory makers will not expand demand drastically. It is in the nature of their business to keep the market under-supplied, otherwise the following oversupply will kill them. Instead, supply is just rerouted from less profitable segments such as mobile and personal computing.

The up-front investment of a memory fab is measured in billions, and takes years to construct and get running. The margin on the chips themselves is terrible, so without scale its not worth even trying. DDR5 is a industry standard that takes some effort to conform to, but the licence fees is a drop in the bucket to the cost of creating a fab.
The fabricators were cautious about increasing production, and slow to start planning. It takes further time to build up capacity, and if the demand drops down, they may end up producing dram at a loss when the market flips over to oversupply. The demand whiplash could kill any company that dared betting on increasing production. See the "bullwhip effect" https://en.wikipedia.org/wiki/Bullwhip_effect which has killed semiconductor fabricators before.
There is a discussion to be had about how to maintain national semiconductor production in Europe and US as a strategic industry, but historic attempts have all failed.
Awful time for gamers and PC hobbyists not fully into AI.
I think it's the opposite. Sure in short term hobbyists are getting squeezed, but the amount of capital that they can put into pushing the edge is small compared to Fortune 500. Sooner or later hobbyists will benefit, especially if the market crashes.

Bought a second hand Dell server a week ago. The entire rig with a 12-core CPU and 32GB DDR4 ecc RAM cost as much as I'd pay to buy 64 GB of DDR RAM alone. I hope there's an end to this absurdity soon enough otherwise the pain will affect other markets too. I read the other day that PC case sales have collapsed by more than 40%.
I have an alternative take. If hyperscalers are using more RAM, and that RAM is not available for consumers, it means all the heavy stuff will happen in the cloud. Why would we want both the hyperscalers and consumers to have RAM simultaneously? Consumers would want more RAM to run local models but then hyperscalers capacity will be unused.
