Google sucking isn’t google’s algorithm getting worse; it’s the internet getting more competitive and polluted. If you magically turned on the recommendation algorithm from 2010 but with today’s internet, the results would be far far worse.
There are many search engines that don't have an issue with the internet being "competitive and polluted". So you want me to believe that the people (Google) with the most experience and knowledge about search just can't handle it. While it seemingly is no issue for most of the upstarts? That's just not believable.
