It used to be if I searched for something like "how to solve a quadratic equation" you'd get a site like Purple Math as the first result because it had few or no ads and information written with care.
Now you get a dozen paywalled sites trying to sell you lesson plans stolen from teachers or worse? An AI parody of an answer. The feeling that you are either being tricked with AI or about to be swindled into a subscription makes the web an ugly place.
