However, it is still the early days and I would have personally gone for a longer-term vision, with
- a more Freemium-oriented pricing to grow the userbase.
- a more openly extensible approach : If you don't want to open source the app, you could at least open-source an interfacing part through which people can augment the usages with custom scripts of their own.
This is before anything else an exploration at this stage.
So is it dust like "des grains de poussière qu'on assemble ?" ;-)
Anyway, you chose the most direct "Data flow Programming" approach. It is neat and works at a flexible level.
However, one of the amazing things about ChatGTP is its ability to remember and respond to incremental "conversational" prompts in a smooth way.
How to integrate this kind of manual feedback-like "flow" within that other more rigid automatic "dataflow" of dust is something to think about, I guess.
It is not just "time for AI-native products!" [1], it is now time for "AI-prompts-native products", and yours are more like platforms than products. This is what I like about them.
A lot of coming pseudo-apps are going to be really just simple prompts in disguise [2]. So open platforms are the way to go.
