The biggest issue is that Google Search kills its own sources, which is shortsighted. Google constantly steals manually curated quality content, and regurgitates it in Knowledge Graph without attribution, such that the people who did all the work to develop and curate that information aren't compensated. The end result: As the web Google stole from dies off, Google increasingly has worse, less accurate sources it has to draw from. Journalists are at the forefront of this, and you can see several countries moving to charge Google for lifting news content to combat this. But there's a lot of other sources on the web that probably won't be so lucky.
