A benefit of microservices is that you can use specialised languages for different parts of the system. The core of your system might be written in Java but you might one to use Python for an ML heavy module. Nonetheless, I tend to agree that in an organisation with 100 microservices probably the ideal way would be to have 4 or 5 based on exceptions where you have modules that need a specific hardware profile (e.g. a lot of RAM) or a different programming language than your core system. Everything else could go into modules in a megaservice.
