What I want to know is why when I'm talking to my wife in the car about buying new shoes do I get a YouTube ad that evening about new shoes, when I never got that kind of ad before.
Are our phones listening to us while we talk in the car, and then ads are generated from that?
I'd really like to know the answer to that question.
Edit: fixed typo, shoes, not shows.

It most likely is. And if it's not your phone, then it's your car (assuming it has been built in the last few years)
Instead of guessing, you people need to learn to use Wireshark and find out for yourself.
No, they don't just listen all the time with an open mic and just send all audio to the cloud. Anyone in cybersecurity would definitely notice that and sound the alarm. There's probably tens of thousands of people watching what these companies and their tech do all day long.
They can get all the data they need through other means, like trackers. Most of us aren't consciously aware of the metric shitton of bread crumbs we all leave behind on the net.
Wireshark may or may not help you here. The proposed mechanism is abusing the wake words, which are processed locally on the device. Each marketing wake word could be processed, set a flag and go back to sleep with no network activity. Periodically a bit array of flags would be sent to the server with any other regular traffic (checking for notifications, perhaps). The actual audio never gets sent. I'm not saying that Facebook actually does this, but it's a reasonable explanation for the behaviour seen in the Vice article.
How would they though? The mic is already known to be always on, and what the servers/back-end are doing with the mic input data is not viewable/known by us on the outside. So how would those 'cybersecurity' people know?

If you're monitoring the traffic, and you start speaking, and you suddenly see packets spewing out of a device every time you talk, that's a good indication. There's indirect methods to analyze it without necessarily being able to see the actual data.
Poking around the PCB with an oscilloscope to see electrical signals will probably be useful too.
Its already established that the mic always hot, and that data is always being sent to the server.
What they do with the data is not seeable by us. That is the point being discussed, do they listen in to conversations and market off of that data to us.

Tell me, how have you established this? What were your methods?
By calling out for the Google assist, without having pushed any button first. It's always listening for the activate/initiate key phrase.

That doesn't mean it's sending anything out through the network connection. The wake word is locally processed.
Doesn't mean it's not, either.
This old article from Vice seems to have proven it, back in 2018.

This entire article is full of absolutely nothing but speculation with no sources and poor experimentation without proper knowledge in the field, software, or equipment. No technical analysis at all. This person kind of has no clue and is taking ignorant shots in the dark to try to confirm preexisting notions. The "experiment" they ran sounds like something my mother would do and then get all bent out of shape and frantically call me about it.
I want the 5 minutes back I wasted reading that.
All of your hyperbole aside, if you're worried about time wasted, you really shouldn't be on the Internet.
