Because they are the way enterprise development is going, think low code, no code tooling like Power Platform, where nowadays you are glueing prompts together.

For example, instead of coding a whole microservice in e.g. Go, Java, C# whatever, you use such a platform.

The API endpoints are defined, and then you connect a bunch of prompts, everything that previously required special kind of nodes (conditions, db access, calling into micro services,...) are now all the same kind of Agent node, where what you want to perform is described in plain English.

Maybe this other tool provides a better overview,
