The man who killed Google Search?

Ex-Google search engineer here (2019-2023). I know a lot of the veteran engineers were upset when Ben Gomes got shunted off. Probably the bigger change, from what I've heard, was losing Amit Singhal who led Search until 2016. Amit fought against creeping complexity. There is a semi-famous internal document he wrote where he argued against the other search leads that Google should use less machine-learning, or at least contain it as much as possible, so that ranking stays debuggable and understandable by human search engineers. My impression is that since he left complexity exploded, with every team launching as many deep learning projects as they can (just like every other large tech company has).

The problem though, is the older systems had obvious problems, while the newer systems have hidden bugs and conceptual issues which often don't show up in the metrics, and which compound over time as more complexity is layered on. For example: I found an off by 1 error deep in a formula from an old launch that has been reordering top results for 15% of queries since 2015. I handed it off when I left but have no idea whether anyone actually fixed it or not.

I wrote up all of the search bugs I was aware of in an internal document called "second page navboost", so if anyone working on search at Google reads this and needs a launch go check it out.

This better echoes my personal experience with the decline of Google search than TFA: it seems to be connected to the increasing use of ML in that the more of it Google put in, the worse the results I got were.

Same here with YouTube, assuming they use ML, which is likely.

They routinely give me brain-dead suggestions such as to watch a video I just watched today or yesterday, among other absurdities.

YT Shorts recommendations are a joke. I'm an atheist and very rarely watch anything related to religion, and even so Shorts put me in 3 or 4 live prayers/scams (not sure) the last few months.

Similarly, Google News. The "For You" section shows me articles about astrology because I'm interested in astronomy. I get suggestions for articles about I-80 because I search for I-80 traffic cams to get traffic cam info for Tahoe, but it shows me I-80 news all the way across the country, suggestions about MOuntain View because I worked there (for google!) over 3 years ago, commanders being fired from the Navy (because I read a couple articles once), it goes on and on. From what I can tell, there are no News Quality people actually paying attention to their recommendations (and "Show Fewer" doesn't actually work. I filed a bug and was told that while the desktop version of the site shows Show Fewer for Google News, it doesn't actually have an effect).
