How many of the apps you use on a daily base have some form of AI integration? In my experience, outside of FLOSS software it is approaching 100%. How many of those did you
intentionally enable it? In my experience, basically 0%. Even worse, after manually disabling it many of them re-enable it after an update!
If, say, Google publishes a claim that "95% of Google Search users have adopted AI", that does not mean that 95% of Google Search users think AI is a core feature of Search they would potentially pay extra for - which is what the massive valuations are based on. The AI Mode is auto-enabled, so the only thing it tells you is that 5% of users are annoyed enough by it that they take the time to disable it.
Some people of course genuinely like it and would indeed pay extra for AI-enhanced search, but a huge chunk of users simply does not care either way. They wouldn't pay a dime for AI, just like they wouldn't pay a dime for the ability to re-arrange the letters in the Google logo into "Oggoel". If AI were default-off, they would not bother enabling it. That is fake demand.
