It's not just ChatGPT that's to blame. The VP of Knowledge & Information at Google mentioned that the younger generation doesn't search for things the same way.

“We keep learning, over and over again, that new internet users don’t have the expectations and the mindset that we have become accustomed to.” Raghavan said, adding, “the queries they ask are completely different.”

These users don’t tend to type in keywords but rather look to discover content in new, more immersive ways, he said.

“In our studies, something like almost 40% of young people, when they’re looking for a place for lunch, they don’t go to Google Maps or Search,” he continued. “They go to TikTok or Instagram.”

Anecdotally, I've witnessed younger people searching on Youtube for a video explanation of a technical issue (e.g. an error code when installing some software), rather than using Google Search. It's baffling to me, but Gen Z has a different way of consuming information.
