Do you believe "micro services" can make a comeback? local daemons with an exposed API, each daemon vibe coded?

Microservices are about separate deployment. Regarding separating the development/maintenance of components, you can achieve that in a monolith by composing it out of corresponding modules/libraries with defined APIs. That’s good practice anyway.

Unless we are planning to deploy them all individually to an expensive serverless platform like Lambda, the coordination challenges and overprovisioning are going to more than outweigh whatever architectural benefit you reap (in human-centred development, micro services are solving an entirely different problem - Conway's Law)

Microservices don’t reduce complexity, they just move it to the interactions between services. You have the same fundamental design problem.

In other words, if you can’t design a modular monolith, you can’t design a set of microservices.

Sure, why not? The same reasons they succeeded originally will work just as fine now.

Please no.
