> Fast forward almost 30 years to 2019. A typical commercial cloud VM “core” is a hyperthread of a 2.5Ghz to 3.5Ghz (turbo) physical processor core with 2GB-14GB RAM per core and effectively infinite storage via cloud storage, though local disk might be limited to 64TB or less. Using the same CPU-to-disk ratio as 1990, that 3.5Ghz turbo hyperthread would be paired to 6.6GB of disk (actually, 3.3GB of disk, taking into account the fact that a hyperthread is really only half of a physical core). The author "controls" for the increase in cores, though. This really is a pretty simple point. A modern x86-64 CPU is not just a 386SX running at a higher clock speed. You cannot compare CPUs across decades only on clock speeds. Nothing works like that.
