This has all happened before, and it'll happen again. In the mid 90s prices went way up (because of Windows 95 memory requirements) and it took over two years before they hit a lower point than they had been previously. There have been some episodes since but not as big as that one (and this one) so people are caught off guard.
If the AI bubble doesn't burst and they actually follow through with even half of the claimed/planned/announced datacenter projects it might double again before it peaks. They have the money to push Samsung/Micron/etc. into converting lines making DDR5/LPDDR5X to HBM, and they'll happily go along because $$$.
I imagine the China memory fabs are greatly speeding up their timelines and will be able to get a lot more capacity online. The US will likely tariff or otherwise block them but that RAM will be able to be used in PCs/phones shipping to the rest of the world so if you live outside the US you might get some relief later next year.
