I disagree as there is a pretty broad spectrum of activities that you might not want broadcasted publicly.
Sexual acts, politial opinions, social opinions, partners, etc, all of these are commonly used to discriminate by all groups. Not wanting to have absolutely everything you do recorded doesn't mean that you're doing something that is harmful or wrong to society; there are a multitude of common situations in which you wouldn't want privately shared information attached to you directly. Examples can be given, but excluded for brevity.
Also given that Amazon has shown that it isn't keeping more than what it needs to catch the summon word "Alexa", it shows that it is very easily and technically feasible to balance "always on services" with privacy. Apple does this with iMessage and it's mobile line. Windows, macOS, and many Linux distributions ship with a disk encryption option. This is something we have a pretty easy and readily available technical solution to that allows people to retain their private lives while having "always on" tech.
When Eric Schmidt wrote that quote, it was defending an ill-fated and misguided attempt to force real names for a reason that wasn't really made clear. It was a very weak justification for the real name policy Google was trying to push across their accounts, a policy they eventually gave up on. I get that there are scenarios in which an always on, always tracked, forever recorded, real name data collection policy can solve; but it introduces far more threatening problems than it solves; I've heard talks given by former detectives and police officers on how mindless data collection is an abuser's dream, and how so many abusers were able to find their victims even after relocation because of things like store loyalty cards being leaked, service integration revealing connections, and so on.
