Awesome charts, thanks! I think it bears out that the multiplier for older hardware isn't as extreme as the newer hardware, right?
Either way, it's going to be a long few years at the least.
Maybe larger makerspaces and companies like Adafruit, RasPi, and Pine should start stockpiling (real) money, and pick themselves up an entire fab full of gear at firesale prices so they can start making their own ram...
