I’m in general agreement that Rx is, in practice, not an improvement over most other approaches. But: > How do I cancel this stuff Everyone I’ve ever heard describe Reactive pipelines describes built-in, standardized cancel behavior as the raison d'être for Rx! It’s super common to encounter a one off someone thought would never get called more than once in a while, which actually piles up a huge serial queue (or worse, creates dozens of threads while concurrently contending for a resource that’s serialized in a less than perfectly transparent way). So in those cases, knowing all your interfaces explicitly include a cancellation token is pretty appealing. Of course, in practice, lot’s of people don’t bother to wire together the cancellation bits, so you’re left thinking you can cancel things but it doesn’t actually do anything. So maybe that’s what you meant...
