What's the worst thing that could happen to Google?
natch: How about...The AI Google is growing becomes "too powerful to fail," a more insidious version of the "too big to fail" we hear from banking. The humans at Google lose control of their business as automation increasingly leaches more money from any business possible. It becomes harder and harder for the Google humans to unwind each ad transaction to determine whether the ad leads people into scams. Users start to step back from their engagement with Google. Alternatives begin to get traction. Humans at Google start to become alarmed. As a defense against the power of the AI, Google transitions over to a new system and allows the old data to fossilize. The new system allows for a higher degree of human input, though it's still not under human control. At this critical point, competitors move in and take away a lot of the market from Google.
