The aim of those buying up all the RAM is to prevent people owning devices capable of serious computing, so we have to rent what we used to have back from them, with added censorship and surveillance. Sam Altman has been explicit about how he wants no one to own RAM except companies running data centres. The Raspberry Pi becoming unfeasibly expensive is just an example of that forced transition from owning to renting playing out. When it was introduced the Pi cost $15 $35. We’re in a different world now.
