Oh they'll sell them all. Big corporations are buying them in mass bulk. No thought put into if it's a good idea.
And yes, the bubble will pop, but those stones will long be sold. It will be the corporations problem then.
And everybody thinks that these companies will have a huge fire sale of used stones, that were never used, after the bubble pops.
But what do you think is more likely? The companies will try to enter the used sales market? Or will they instead trash all of them, and write them off in their taxes?
There's precedent too for this exact situation. There's a landfill will thousands of E.T. Atari cartridges, because some genius took a terrible game that nobody wanted, and produced a number of cartridges that exceeded the number of consoles by 4 to 1. For a game that was never going to have even a 1:1 ratio, much less 4:1.
So now they're in a landfill. Just like all the ~~ram~~ stones will be.
