First of all, passwords aren't going away any time soon. They are required for the web, as @Parody helpfully pointed out, not to mention syncing to the server. So any changes will come after lots of other things that are higher priority.
Also, I've learned to ignore all the calendar references. I just thought it was cute the way that @weogarth inserted them in his post. I'm working around the clock these days, and I'm punchy, so I commented on the approach.
