To quote one of Akin's laws which were on HN yesterday, "better is the enemy of good".

It's really good when one technology is used throughout an organization to achieve the same purpose. At some point, the technology you use is actually good enough, and incremental improvements to "keep up with the times" are simply distractions from the real work. And if at some point you find that your tech has truly stagnated, at least you're stagnated together, and can modernize together at the same time.
