I'm going to focus mostly on their SE. Google's success is hugely based off their years and years of data collection, meaning no company starting now will ever catch up. I understand that history has shown how unlikely it is for a company to truly be unmatched, but when huge sample sizes of data that can only be accrued with time and no other means comes into play, the situation is different. This issue of time is made even worse knowing that Google's engine would be a pain to try and recreate, given their decades of optimization. If you're someone who A) wants to match google's data and B) catch up to the competency of their search engine, you're looking at 20+ years of work all while google continues to improve their current search engine. Many PhD's have gone into ensuring Google's SE is perfect down to every last decimal point. It would actually be impossible to make an exact copy without direct theft. "Google will fall once something usurps their dominant platform advantage ( chrome/search/android )." I question whether this is a matter of "when" or whether it's actually a big "if". People will be able to provide alternatives to google but i don't think there will ever be another google.
