I think a common issue with cargo-cult technologies/languages/frameworks is that although the ultimate benefit might be great, there is often a significant cost to get there that makes it not worth it for some people/companies. For example, is Go a great language? No doubt. Is it worth ditching a load of code we already have and take the time to learn how to do it well? Not necessarily. Are microservices cool? Absolutely. Should everyone use them? Definitely not. People who see "Go is great" and immediately start down that path do not understand that context is everything.
