I wouldn't agree that Deno showed that, as I said many companies are making a lot of money from non-Node JS runtimes.

The players I mention have built their own runtime, they're mostly all built on V8 isolates (including Deno Deploy).

This is why I struggle to see where Bun fits in the edge JS world, as far as I understand it JSC has no Isolate primitive meaning Bun would have to write this from scratch (or salvage the other parts of WebKit that offer isolation). Otherwise Bun will be limited to using Linux containers on the edge, at which point you re-introduce the startup time you gained by switching from node in the first place.

Someone suggested that Deno Deploy might not be using isolates as isolation boundary per account but processes instead (though, Deno Deploy may be using isolates to run different functions part the same account).

JSC definitely has things resembling isolates.
