All this is documented in Meijer's actual paper though? (Your mouse is a database) as well as his aformentioned talk (duality and the end of reactive).

He for sure invented observables (as we know it and as the mathematically dual of enumerables) - that doesn't mean it was the first ever reactive system or the concept of data being dependent of other data.

If I remember correctly he also explicitly talks abut Conal FRP and notations in https://www.youtube.com/watch?v=pOl4E8x3fmw if interested

I have seen plenty of Erik's talks and certainly read Your mouse is a database a bunch of times.

What is "documented" there is the alternate history of all this coming out of fundamental insights into FP and dualities and all that.

But that isn't the case, it just sounds a lot better than "I found a really complicated way to map dataflow onto FP concepts".

But we as an industry just love complicated.
