It seems that every few years a new backend language comes to the forefront and becomes a popular for greenfield projects or rewrites. First people moved from PHP to Ruby, then Node, and now Go.

Of course, Go's popularity is helped a great deal by Google using it, as well as the huge amount of devops software written in Go (docker, terraform, kubernetes). But at some point the hype for those will settle and they'll just become more tools. At the same time there'll be more and more legacy Go projects at various companies that won't be very exciting. Around about this time we'll probably see the next language start rising in popularity.
