I checked again to get a more up to date report and so that we actually have something to go off instead of my memory of some random reports. Pew finds 50% of people use chatbots and the most common use is searching for information. Also in the report the have a stat for reading AI summaries at the top of a search and that is 60% say that have, 10% dont know and 30% dont read it. https://www.pewresearch.org/internet/2026/06/17/americans-and-ai-2026-chatbots-smart-devices-and-views-on-impact/

So its fair to say I was wrong and its not over 50% but its close to 50%.
