But email has been working for us for _(many)_ years. What do we need (or want) email to do that it doesn't already?
Bundles? I already successfully, with minimal effort, manage personal, business and sales-related emails. I don't need an algorithm to do that less well than I already do.
Highlights? Ok, maybe. I have a decent working memory, but maybe finding and scrolling down to the email from Delta and then tapping it open is too much for some people. Not me.
If the Assists bot is as "good" as google maps's, no fucking way do I want it trying to find me a phone number or tell me business hours. I already have emails to myself (don't worry, I save them as drafts; they aren't sent) and google calendars (and OMG I hear some people actually use post-it notes!). What functional difference does the snooze/reminders service offer? I'm very good at ignoring an email until such time as it needs my attention.
In other words, this is a solution (maybe) to a problem that doesn't exist for many of us. There may be some people who have a thousand emails a day and they can't manage it. I'm not convinced this is will solve their problems, but for the rest of us, it's just a non-event. Moreover, it's not because I'm opposed to innovation, but many earlier efforts that were hailed as game changers or amazing advances in AI and big data (or bloody political Change) turned out to be little more than marketing hype and hyperbole.
The current solution works, and until something can demonstrably improve upon that solution, it will be met with the doubt and incredulity it deserves.
