> And those companies all realized they can make billions more dollars making RAM just for AI datacenter products, and neglect the rest of the market.

I wouldn't ascribe that much intent. More simply, datacenter builders have bought up the entire supply (and likely future production for some time), hence the supply shortfall.

This is a very simple supply-and-demand situation, nothing nefarious about it.

That makes it sound like they are powerless, which is not the case. They don’t have to have their capacity fully bought out, they could choose to keep a proportion of capacity for maintaining the existing PC market, which they would do if they thought it would benefit them in the long term.

They’re not doing that, because it benefits them not to.
