I wonder if new serverless platforms, like Modal [0], are even simpler than monoliths. I've been reading some books on software engineering, and it seems clear that network calls, multiple services, integration points, etc. all cause complexity.
However, I do wonder if things like Modal allow you to focus only on writing business logic. No dealing with deploys, network comms, memory, etc.
(No, I don't work at Modal, just wondering "what comes after monolith" -- Modal, Temporal, etc. all seem quite good)
