On a bit tangential note, RAM price for a given cost used to increase exponentially until the 2010s or so. Since then, it only roughly halved. What happened?

On a bit tangential note, RAM price for a given cost used to increase exponentially until the 2010s or so. Since then, it only roughly halved. What happened? https://jcmit.net/memoryprice.htm https://jcmit.net/memoryprice.htm I know it's not process geometry, since we went from 45nm->5nm in the time, a roughly 81x decrease. Is is realistic to assume scaling will resume?
