Hmm I don't think SEO spam and fake reviews are Google's only problem. These have been useless for a long time, but I believe they're altering search results on purpose just to give you more crap to click on.
Random example: paste a stack trace in google, add, say, raspberry pi. First 5 pages of results will be beginner tutorials on how to set up something on your Pi. If you're lucky you'll get something related to your stack trace in the later results. Sometimes you don't get squat.
