RAM prices aren't coming down until the AI bubble bursts. It wouldn't matter if there were another dozen companies manufacturing RAM if the global manufacturing capacity were the same. Even if some of those companies were willing to build additional manufacturing capacity, it would take years for it to come online because erecting the facilities and installing the equipment to produce the chips is also constrained.
Fortunately, everyone seems to be waking up to the fact that AI isn't a silver bullet and realizing it won't solve all of their problems or even save them any money. Also, for anyone playing older titles such as some of nearly three decade old games listed in the summary doesn't need a new machine with more RAM. Installing Linux on older hardware that Microsoft doesn't want to support has always been an option.
YotLD is every bit the meme it's always been and even if Valve had a popular Linux gaming machine at a reasonable price, it wouldn’t move the needle in a meaningful way. Desktops are becoming increasingly irrelevant for most people and Android is the dominant mobile OS that a majority of phones around the world use. Eventually most people will run Linux on desktops, but only because they've become irrelevant for anyone but the kind of power users that want a *nix box for professional work.
