Just look at the military decisions Hitler made, that was luckily an incompetent guy thinking he’s smarter than everyone else. That rings a bell, doesn’t it?

In the long run, making less stupid decisions wouldn’t most likely have changed the outcome, but even more people would likely have died (and unfortunately the people executing the murder of the Jews weren’t as incompetent as their glorious leader).

A phone reacting to “ok Google” or the equivalent for the other assistants already requires to listen to what you’re saying - doesn’t seem to affect battery life all that much.
