The 1990s were the peak of "you will be able to buy a better computer in a year and a half" and "the cost of computing power is going down rapidly" and, for me, the 2010s were the decade where you couldn't sell specialist VCs on any non-columnar query engine because they were all impressed by mechanical sympathy, more so than the mainstream programmer. Today we're in the age where we can't count on your next computer being faster than your current computer or being more affordable, so the trade-offs look quite different -- it is feeling more like the 1980s where the Apple ][ line lasted almost a decade longer than Apple expected with (mainly) minor improvements in performance.
