(thinking emoji) they could merge.

Seriously, they're both Rust now. They share goals.

I doubt it would work out. The engineering cultures could not be any different.

well bun could 'gradually become deno':

1. add 'enhanced security mode' that's actually 'deno-compatible/like' (permissions, etc)

2. mark libs/executables/etc as 'enhanced security compatible'

3. ...merge by buying out deno?

They may share some goals, but also have differing and opposing goals.

But it's possible that all 3 Deno, Node, and Bun could share some code in the future considering they now all require Rust as part of their build process.
