Microservices exist because of the limitations of a single human brain in being able to wrangle with that much logic at a time.

It is perfectly conceivable that an alien species with different brain characteristics would draw their microservice boundaries at very different points, possibly varying by a whole order of magnitude in either direction.

I don't agree that there are organizational causes even though that's oft repeated as one of the main reasons. I have never seen a one-to-one relationship of microservices and teams irl. Most teams own many services and some services get touched by many teams. In big companies, there are also microservices with zero owners.

One team owning many services is fine, as long as they can deploy them independently of any other team. Less critical (but still useful) is being able to deploy their own services independently of each other.

Except microservices don't do that. You still have to wrangle other people's system parts.
