Hard to say, but the programming parts are fairly general and low level so the ideas should transfer pretty well. E.g. there are numeric values, mathematical operations, logic gates, etc. It can perhaps be compared with LabVIEW.

My main worry with Dreams is that it is a closed ecosystem, which is always a minus in my book. So far it does not feel exploitative at all, and Dreams does have some cool "under the hood" features such as OSC support. I don't think the studio itself is likely go evil, but in the end they are owned by Sony...
