Google search still works well for many things, but is SEO spam/bot infested for anything that requires a hive mind opinion about something from mostly genuine people. Like if I want to know what kind of a best in class/best bang for buck/newest [insert product] to buy and have no idea where to start, Google is often the worst place for it. I'm not sure if that's because most opinions like this are shared on social media like reddit (and in rather unstructured form) instead of on blogs/websites that Google mostly indexes, or if it's just really difficult machine learning problem to formulate something resembling a non-spammy consensus opinion from experts by just crawling shitloads of websites that all try to SEO spam the crawler
