Don’t hold your breath. The zircon API isn’t innovative in any modern sense. Additionally it’s bloated and not clean like L4. It’s just in house IP for Google.

(HN won’t let me directly reply to the comment below so here it is:

Nothing in zircon doesn’t already exist on Linux or any other modern kernel. Additionally it has bloat, like 3 distinct IPC mechanisms.

Even further, if it ends up being any technical person’s main driving OS it will surely sport a POSIX API and at that point it’s just another implementation of POSIX with similar a security model.)
