Future of Voice and Audio

All elevators, doors, faucets, and handles will go to voice or gesture based activation as standard. The technology now exists for hands-free everything. This is going to be hygiene 2.0 across society, at least in Asia.

As someone who very much enjoys podcasts I continue to be frustrated that so much information is locked up in opaque audio files. How do we make all of this information accessible, searchable, navigable, linkable, upvotable, etc? Great opportunity if someone does this right, imo.
