I think it's going to kill free search engines because it can go do a search on all of them at once in seconds and no human will ever see those ads.

So sites will move to paywalls or aggresive WAFs and those LLMs will become useless at the same time succeeding in killing search engines leaving no viable alternatives.

Already half the public internet is inaccessible without allowing to be heavily fingerprinted and be tracked just to prove you are a human user.
