"Thrun predicts we'll have reliable urban robot driving by 2010, and that a majority of miles will be driven autonomously by 2030. You'll have more time to answer your e-mail, and arguments over who's going to be the designated driver would be a thing of the past."
Why even bother answering your e-mail? Just give your PC--- which by this time will be smarter than you and have a better personality---a general idea of the sort of the answers you like to give and let it answer the e-mails itself.
And FreeRepublic will be ruined, full of Bushbots exchanging talking points, or worse Gorebots continually signing up for the zot.
