Let's consider only "safe for work" Internet content:<p>Google/Bing have done well with keyword/phrase searching with results sorted by popularity and date.<p>Ng seems to be thinking that the big change will be having speech and images coming from the users as their input to the search process. My guess is that this will not be very important. I also guess that search for Internet content based on speech and images will become more important.<p>Yes, likely Ng can get a lot of pictures of what he knows to be, say, Ferraris and use some of them as the <i>training set</i> with a neural network to
identify Ferraris and test the training with the rest of the pictures. Okay. Maybe his neural network will be able to identify Ferraris. So, he could repeat this training for, say, 100,000 objects -- Fords, bread, airplanes, jewelery, Victorian houses, .... Maybe there will be some value there.<p>My view is that the future of Internet search is quite different.
