    This kind of invalidate the pitch of Pi, the self-modifying harness. You can't use the Pi extensions I'm assuming...

    Without a plan of your own for extensions this is comparing apples to oranges. My Pi startup time is dominated by loading extensions and skills, and I don't even have many to begin with!

    (It seems like there is a pluging API judging by the Github repo. That wasn't linked in the comments by the time of my writing)

      I wonder about adding a plugin shim for webassembly, or a Rust crate with integrated V8 engine (Bun?)

        I mean, kinda same. I've asked it to write skills but that is about it. And skills dont require this. But I do use other peoples extensions.

          I suppose one potential drawback is that the visibility of the logic of a plugin is inherent in the pi ts extensions, and unless it's shipped with the rpi (pi-rust) extension, it may not be the same.

            There is a tool named Docs that guides users on how to use RPi and how to write extensions. RPi has a plugin ABI to support extensions.

    That name won't be confusing at all

    Nice!

    This is great. A few days ago we were able to enable running Pi fully in the browser (and in the iPhone). Demo here: <a href="https:&#x2F;&#x2F;wasmer.sh&#x2F;?example=pi" rel="nofollow">https:&#x2F;&#x2F;wasmer.sh&#x2F;?example=pi

    I&#x27;d be curious if we could compile Rpi to WASIX (<a href="https:&#x2F;&#x2F;wasix.org" rel="nofollow">https:&#x2F;&#x2F;wasix.org) and get it there as well!

    How would you handle a co-founder whose commitment appears to have changed?
