Even as a proponent of what I perceive to be the core concepts of microservices, I think building hundreds of very small ones is a bad idea

I'm seeing the move to Lambda/FaaS break down services to collections of much smaller functions. Seems to be productive so far.

Definitely the future model in terms of infrastructure support, I won’t disagree. I still think a larger “unit” is needed, too

we will alway have a mixture of external services, VM's, Containers, and Functions as first class components to build apps.
