I think Schmidt has an important point... we collect like Digital Karma! One (big) mistake in live could hunt you down for the rest of our lives with help of Google and Social Media. Employers (HR) are already tapping in to this source to double check a candidate. Yes, I believe that more and more people will try to re-invent themselves, get new ID's names if possible etc.. although it will be not much more than a desperate attempt to escape the digital karma.
