If hardware speeds and capacities had continued to increase as rapidly as they used to, there might have been some truth in that. Buying a computer with a faster CPU or a bigger disk or more RAM was a relatively cheap solution to a lot of performance problems for a long time, in no small part because it typically required zero changes to the software itself. However, once you're talking about qualitatively different hardware architecture (scaling out instead of up) and therefore also qualitatively different software architecture, it's far from obvious that the premise still holds or that we should even expect it to.
