This is certainly a true statement - but there are known technologies that provide better characteristics for scale than others (looking at big scale names such as Netflix as a start). Simply writing it off as “well they scale so fast, whatever!” is completely sidestepping the issue of using knowingly error prone tech at scale, and frankly is a bit irresponsible. (Note: this isn’t a statement on what CB uses or if they’ve tuned it appropriately or not)
