Yes, I know. This view is how these problems are always perceived, decade after decade, as our predecessors filled rooms with iron and silicon, unable to fathom that the equivalent capacity and power would be a portable device 20 years later. We're not at some end point in this process: the devices we have now will appear just a primitive in the years to come as a 10MB 5.25" Winchester drive appears to us now.

One of the underappreciated effects of the AI boom and associated money is that it has strongly reinvigorated R&D in hardware: it is clear that there is a real application for far greater density and lower power demand, and people are now pursuing this much harder than they had been. That will yield what it has always yielded; orders of magnitude jumps in capacity and performance.
