RAM prices won’t stay like this forever. If demand keeps up, suppliers will just start producing more.

So I guess the price should come down substantially in about two years.
(Except if the data center demand keeps growing to eat up that increased supply. But at that point the bottleneck might shift somewhere else, e.g. to TSMC and processor manufacturing.)
Building a modern chip fab takes many years, and no one seems ready to take the plunge yet. The existing suppliers are happy to just keep raising prices instead.
