I always assumed that the personal-agent style work (ie a bot that is there to help you wade through the morass of information) would be a personal computation - local to you, probably configured and augmented by you.<p>Yet Google is trying to do it for everyone - and honestly does not seem to be doing a bad job.<p>So what is the advantages of the old idea of an almost-AI assisstant working for me when BFG (Big Friendly Google) does it?
