I think the whole area (rightly) suffers from "Bikeshed" syndrome - this is something everybody can have an opinion on, and 90% of the time their opinions are right for them. At work you know someone who schedules appointments with themselves just to block out some time, or schedules meeting with you because emails don't get a response and ... The solution is not more protocols, or opinionated software. The solution is that every individual should have the skills (software literacy) and the infrastructure (some combination of a diary server with an API in fifty languages) and tools (come on iPhone, really whatever you are doing it's a total mess) At some point with Mailbox any coder will have built an sub-AI agent from 200 regexes - and that's probably what will smoosh out across the world - oh yes I let my Virtual AI / PA handle that, it was coded by my brother in law and I made a few config changes.
