> Their search engine is really hard to replace, not just because of the quality, but also because of how ubiquitous it is. For the web, yes. I'd argue it's not threatened by other search engines, though it is threatened by other players and indexes: - Apps. Google can't crawl apps, and people are getting used to the idea of finding information in separate indexes as opposed to a single universal one. Each app today has it's own search box, so if I'm looking for somewhere to eat I go to Yelp. A product? Amazon. If I'm looking for someone I open Facebook. If I'm looking for flights I open Kayak, Priceline or Expedia, etc). > YouTube is the second largest search engine on the planet and has the largest mindshare of any website on the internet. I agree that YouTube is very strong. > Android is "the" platform pretty much everyone accesses the internet. I disagree here. People largely access the internet (as in, data from the internet) through apps, like I mentioned before (Yelp, Facebook, Amazon, Kayak, Expedia...). [1]. Moreover, in terms of OSes, you still iOS and Windows are still holding steadily to a decent chunk of important markets. > Cloud could do better (it's 3rd distant in the race against MSFT and AMZN), but nevertheless a huge opportunity. I do agree here. > Buffet and Munger were correct when they commented about Google saying they'd never seen a wider moat in their entire career. +1 on some things, but not so much on others IMO. At this point most tech companies have comparable moats. Amazon, Facebook, Apple-- also huge moats. And that's the thing-- competing against "just another search company" they're definitely in no threat, but they're competing against companies about as moated as they are. Amazon beat them to the punch with voice assistants. Apple Music is taking market share like Google Music couldn't. ChromeOS still can't seem to crack the dominance Microsoft Windows has on laptops. They're a lot stronger than most people think, but their competition is too. [1]: Fun fact, people browse the web a lot while using Facebook. This is somewhat tangential to my main point so putting it down here, but Facebook is actually a major web browser: https://techcrunch.com/2018/08/06/facebook-is-now-a-major-mobile-browser-in-u-s-with-10-market-share-in-many-states/ https://techcrunch.com/2018/08/06/facebook-is-now-a-major-mo...
