<@U0Z3X3AN6> IO does not have combinators for streaming. that will come as part of the work done in `arrow-strreams` which is something you can compare to Rx2.
If you are using Rx just to assemble components of your app with flatMap etc then it's about the same. You can also write your programs in a polymorphic way and then you'd be able to run them to IO or Observable without changing the code: <https://arrow-kt.io/docs/patterns/polymorphic_programs/>
