Look at it this way: while the upfront cost to scale up production is huge, prices are now high enough to justify it even if demand is expected to drop abruptly later on. So if you can wait 5 years for your next PC, 1TB RAM might go for what 64GB would have cost without the AI demand spike.

Granted, if you need a new system before then, you're SOL.

One thing to look out for is supply capacity curiously going offline in 2030 or whatever. That would hint at market power or collusion.

Memory prices per GB were cheaper in 2012.

It’s possible we’ll see a huge price drop on the near term but SSD + Cache + GPU’s seems to have changed the equation where RAM speed is considered more important than size. And from a pure architecture standpoint it makes sense.
