I like the article, but not your title. It implies that this trend of I/O becoming highly performant has occurred recently, when in fact has been observed and studied for quite some time [0, 1]. Even before SSDs Gigabit ethernet was saturating CPUs needing to do more than DMA a packet, and I'm sure this trend continued for some time. The original title seems more accurate: "Implications of the Datacenter's Shifting Center", and references the existing trends in an insightful article.
