Half of the jobs I'm applying to have microservices in the description, much more often than, say, REST or Boot, so somebody definitely thinks they're a general solution to something.
I went through some interviews where they put microservices in the job description but when asked it turned out to be a kind of monolith for core + a set of other services for other stuff (authentication, logging, analytics).
Microservices is an excellent generator for developer busywork and increased headcount. Busywork benefits the developers, increased headcount benefits their manager, and so on.
