My first thought: in 2030 when I’m calling grandma with this, I will first need to accept cookies, then accept the new Google privacy policy, then sign in to my Google account, then watch 2 20-second long pre roll ads.
We're witnessing a magical tech demo here. If Google actually releases it and hinder it with ads, sign in walls etc., it's not magical anymore. If they then cancel it two years later, it doesn't even exist anymore.
We can pretend that this will be Google's magical fairytale product that will not be impacted by the above, but who are we kidding?
