The user demographics changed a lot. When google started, most people didn't even use the internet. Today, most people go online to shop, watch videos, or socialize. Today's Google serves that target pretty well, at the expense of the relatively small number of people who are searching for technical information about programming languages or frameworks.
Not coincidentally, a lot of ads target that demograpic as well. So naturally google's top results are also ad-laden.
Google still serves me well when I look for technical information, but do you know a search engine that's even better for that purpose? (I also use ChatGPT, and that's sometimes better, sometimes worse, and always slower.)
