Wait until they realized that solving their spaghetti problem with microservices resulted in them operating an Italian restaurant.

Pushing complexity onto interprocess/machine communication will just result in higher levels of spaghetti. Do you really think that same people who would construct a monolith poorly would do a better job building a distributed system instead?

I don't mean to be too dogmatic; there are legit use cases for services. I am just highly skeptical of microservices as a solution for complexity.
