    nice post :)

    I’m surprised there’s not been any mention of effect (http://effect.website/) yet, as it is kind of the next level up if you really want to model things like errors, dependencies and side effects in the type system, using functional concepts borrowed from more pure functional languages.

    It would be a bit of a risk adopting this into a shared code base depending on your team and the kinds of devs you’re looking to hire, but it could be useful to some folk that feel like they want even more type safety.

    7. As this is such new territory, a lot of the tooling we need doesn’t exist yet and we have to build it ourselves.

    What is our answer to these? How will we win?

    In short - good old software engineering.

    Longer Answer:

    - We’re making heavy use of [Effect](https://effect.website/), which allows us to gain as much control as you possibly can in such an undeterministic environment. Also, it will enable us to represent complex agentic workflows while keeping a deep level of observability.

  • Understanding React Compiler

    I think React would get better developer experience and performance if they adopt language coroutine feature to implement direct style algebraic effect. In fact the React Fiber system is already an implementation of algebraic effect.[1] However, it’s “suspending” a routine by raising an exception. Thus unwinding all the call stack, therefore, it needs to re-run that same routine on resume. This is the core reason why they have a performance issue and why they created the compiler to cache values on reruns.

    JavaScript has language level coroutine features like async/await or yield/yield* and we have seen libraries using these features to implement direct style algebraic effect. For example Effect[2] and Effection[3]. You don’t need to memoize things if the language runtime can suspend and resume your functions instead of throwing exceptions and rerun them.
