It's not the people, it's the companies. They invested billions (trillions?) into data center expansion and development, and discovered few people willingly turn on their heavily indebtedness AI features - so instead of reading the wall they made it a default feature that most never asked for. Now they can claim billions of users of AI when in fact it's just a feature that runs whenever you interact with the UI.
Now AI corps can say 'Look, we have all these users to justify our wreckless hoarding of computing resources.' Just look at search engines, for example Google defaults to running an AI query on every search. This is such a huge waste of resources. Although sometimes it is admitedly useful but that is the other problem - the search engine is now also the final destination page - once popular web sites with actual useful information will go dark since no one visits anymore.
