Can anyone speak as to why Netflix needs so much computing power? As far as I can tell, content delivery is handled separately, so all these talks are about the non-content side.<p>Sure we need to see various personalised lists when first connecting, but no activity while actually watching things. The personalisation seems very light - eg their lists of comedies look like they show the same to everyone. And it doesn't seem intelligent at all, like for example hiding items you have already seen. <a href="https://news.ycombinator.com/item?id=9083196" rel="nofollow">https://news.ycombinator.com/item?id=9083196</a>
