Video conferencing is pretty bad IME. I think that all too many companies view Slack as an acceptable option for communication most of the time, and I think that's an extremely inhibiting factor for most remote work. I think some innovation around the tools we use for remote work would be great, fwiw.
For example Teams and Outlook have terrible search. Documents basically go into a black hole to never be seen again. We need the same search quality we have for web searches.
that's why you shouldn't use _either_ of those as repositories of information ... they're great for the ephemeral discussions, but once consensus is reached, you should have other ways of tracking that, whether it's: github/devops/jira issues and tickets, or some kanban board somewhere, or design documents, or a wiki. The discussion itself shouldn't be the artifact that records the decision.
What I can think of is a smartphone app that's always listening and transcribing, best-effort, all it listens. This can capture in person speech and make it searchable.
Also, are any of the current videoconferencing options offering machine transcribing out of the box? I know users could always hand-feed recorded video to a separate tool, but ease-of-use matters.
Emulating face-to-face-ness remotely is precisely the hard problem. As pg once said, the real world is incredibly high-bandwidth.
There are tools like automatic captions + manual tagging that can make search much better. The tools are out there, just not well adopted at this point.
