As I asked someone else, what is your methodology here? Have you limited all variables that can cause Google to collect this information and lead to confirmation bias? Did your wife search for prices of electric blinds on Google after you both talked about buying them (a very natural and logical next step after discussing the need to purchase them)? A random conversation, or 20 of them, with your wife isn’t exactly a controlled experiment.

Again, I’ll mention that Mitchollow attempted to conduct a genuine controlled experiment to determine whether Google was listening to him through his microphone. What he failed to realize was that he was livestreaming this experiment to YouTube through Google’s servers, the very conspirators he claimed were listening to him, so he was already voluntarily giving them all of the audio data they would ever want! When this was pointed out to him he retracted his statements, admitting the experiment was intrinsically worthless by design.

I’m not being naive, I’m skeptical of these claims and challenging the veracity of the anecdotal evidence presented. To blindly accept yet another anecdote that confirms a bias of ours whilst rejecting differing skeptical opinions would be closed-minded.
