One of the advantages of Google hosting this (as opposed to, say, this technology being an "out in the wild" agglomeration of voice synthesis and machine learning open-source solutions bailing-wired together) is that there's one central authority that can be held accountable.

You're not going to see the described scenario because there's nothing in it for Google, they have full control over both the Google Assistant ecosystem and the set of technologies powering this machine-learning interaction, and they can gate-keep it as much as they want to.

That having been said... If one company can do it, we're only N years out from the tech becoming available "in the wild" as a bailing-wired selection of open-source tools (probably in a Docker image somewhere ;) ).

Even if not another company, people develop actions for Google Assistant so I don't think it's that wild to think that 3rd party Duplex behaviors could be something Google is considering.
