Bubblewrap is a less powerful version of sandbox-exec, but the macOS architecture is much larger than just that. In effect macOS runs everything under bubblewrap, in such a way that users don't notice but apps are meaningfully sandboxed and root exploits barely matter.

replyBubblewrap isn't a sandboxing architecture, so no. Go look at how Apple designed the macOS/iOS security system and you'll see that a Bubblewrap like tool is only. small portion of it.
replyLinux in-general is a small portion of the Darwin architecture. One is a monolithic kernel, the other has microkernel IPC security to consider.
replyAre there any glaring limitations in Bubblewrap you'd like to point out, or are we having the Tannenbaum argument all over again?
