问HN：推荐系统是不是变得更糟了？
我觉得我在Instagram、YouTube或商店上看到的所有推荐内容都非常无聊，都是一些千篇一律的东西。<p>YouTube就是一个很糟糕的例子，观看一段关于某位艺术家的视频后，推荐栏里就会充满关于那位艺术家的内容。而且这些“推荐”是无法去掉的。<p>其他大多数平台也是如此。如果你有特定的需求，情况甚至会更糟。如果你寻找某个特定的高端品牌，它仍然会推荐一些低端的产品。如果你是左撇子，它仍然会推荐右撇子的东西。<p>这对平台来说到底有什么好处呢？是什么阻止大家向用户展示好的、有用的相关推荐呢？

I feel that all my recommended contents, like on Instagram, YouTube, or in shops is really dumb more-of-the-same.<p>YouTube is a really bad example, watch one video about one artist, the feed will be full of just exactly that artist. And one can’t get rid of those “recommendations”.<p>But the same is true on most other platforms. It’s even worse if you are somehow specific. If you look for a specific premium brand, it will still recommend low-end stuff. If you are left handed, it will still recommend right handed stuff.<p>How does this really convert well for the platforms? What seems to prevent everyone to show users good, useful relevant recommendations?
