Serial compute isn't doing the double-every-18-months-in-speed since something like the early 2000s.
Unlike with serial compute, not all problems can be solved, run faster, with parallel compute. But at some point, unless we figure out some sort of new way to play with physics, we pretty much have to move to parallel compute where we can if we want much more performance.
Lenovo is stockpiling memory to try to make it through the RAM winter.

I don't think that Lenovo is getting special deals with memory makers either, or they wouldn't need to stockpile.
