I have to wonder if they just give us the illusion of being useful.
Just had an email asking if I could meet "tomorrow at 5:00 PM, or would 6:30 work better?". The suggestions were "I will be there at 6", "Tonight works" or "Either time works", only one of which is even valid! Maybe for every time it saves me a few seconds, there's at least one where I have to read them all and realize none fit before writing what I would have done without the quick replies.
