I wouldn't say "never," but it's very likely that RAM prices will not return to pre-AI (read: bullshit) levels. Many markets do this; hike up to crazy levels during a boom, come back down 80%, rinse and repeat.
The only thing that might put a stop to it is competition or the unicorn business that focuses upon everyday consumers and not purely profit (lol). I'm hopeful China is able to be a spoiler to this current tech hegemony, given general US hegemony is basically over, but the home computing market is probably fucked in the meantime.
