To the best of my knowledge, node-based took off because it replicated the experience of using patch cords with physical equipment (like analog synthesizers, likely many other early analog hand-reprogrammable systems). As those analog systems were rebuilt in the computer, it was somewhat natural to replicate the interface. Don't know why sheet-based programming didn't similarly take off, but perhaps because there wasn't as much usage of sheet-based physical interfaces for electric systems in industry.

Sounds like Onex is on this path http://object.network/onex-app.html @Duncan Cragg

Hi, thanks Christopher! In that doc, I'm trying to guide normies, who probably have come across spreadsheets, towards what I'm doing, which has enough similarities to them to make this a reasonably short journey, I hope! There is thus a commonality between the Excel Lambda stuff and my own shared rule objects, but it gets a bit thin at that point!

Yeah, Excel Lambda is barely a step - there's clearly a much bolder vision available, using an entire thinking space that's programmable, that also has all the natural ease and traction of a sheet

That sounds like my vision .. yet to be achieved, but I'm working on it.. 😄
