Every time I read some technical description about why this isn't happening, the technical description seems convincing. However... A friend tested the theory a few years ago. He doesn't own a swimming pool, doesn't want to, and has never expressed any desire to. He put his and his wife's phone on the table and said to the wife (loudly), "Why don't we look into pool fencing?". She agreed with him. Shortly after, on b…

Yup - having worked at Google Display Ads (arguably the epicenter of such talk), I personally only ever witnessed people walking the walk, privacy-wise.

This story was widely reported, but it's a little questionable. The slides are genuine, but they seem more like a prospectus for something Cox wants to do than something that they're actually doing. The presentation also never claims the "always listening" that people are concerned about, and instead just refers to "a data trail based on their conversations and online behavior" from "smart devices." The idea that this is smartphones listening to you pervasively is entirely something people have read into it, not something the slides say or even really suggest. I think most readers in the industry find it far more likely that they are describing reanalysis of consumer interactions with voice assistants (probably not even of the audio but of the transcript). That would presumably be the one in the cable boxes their parent company distributes, because access to that kind of data from other voice assistants seems difficult to negotiate and they do not claim to have it.

If you review the actual presentation (https://www.documentcloud.org/documents/25051283-cmg-pitch-d...), none of the claims in it are that remarkable. The whole kerfuffle seems to have come from a combination of the presentation actually being incredibly vague (probably intentionally to allow them to overstate the capability---this is a presentation for sales pitches) and some confirmation bias on the part of 404 Media, reading into it what they were looking for. But there's also a healthy amount of "news laundering," a lot of the articles cribbing off of 404 (like this techtimes one) actually make stronger claims than the original 404 piece does. It has a fair amount of weaseling that it's not clear how the slide deck should be interpreted, whether it's a real or speculative capability, etc.

If you've ever worked in enterprise software sales, you would be extremely wary of interpreting the slide deck the way a lot of these articles do. It reads like a lot of bluster.

My wife and I, just being goofy, have an inside joke featuring a relatively uncommon name that we ocasionally yell out, like a few times a week. Two months ago we got junk mail addressed to UNCOMMON NAME + our last name.

I don’t think its a coincidence. Something is listening. Its kind of messed up that I am a normally rational, skeptical minded person, fairly knowledgable about information security and in 2024 I can’t even draw any clear lines between a nutty conspiracy theory and reality.

I’m sorry but I don’t find this article basically just saying “yeah but what are the chances Apple would do that?” persuasive at all.

I have successfully argued this for at least a certain class of devices. Namely, it practically can't happen _for small devices_. e.g., a TV remote with a voice feature activated by a button simply won't have enough _power_ to constantly be listening, uploading, or processing. Harder to convince folks that _nothing_ does this, but takes an edge off their more paranoid tendencies.

I personally don't believe any argument that says it's not feasible. Transcribing all spoken text and sending it home, sure, not feasible. What if we have 256 keywords, or 65536 keywords, maybe preconfigured for particular products or product classes. Some basic linear predictive coding mechanism ( you know, what powered those '80s chips Stephen Hawking style, speak and spell, etc) - very very low computational overh…

For sure! I mean, my Google pixel has "Now Playing" which is able to passively listen to the microphone for songs it knows, and displays them on the oled lock screen.

So, we already know that it is

A. completely feasible for a smartphone to do this.

B. At least a subset of smartphones have always-on microphones.

Maybe not a remote control... But why would you put it in a remote anyways when everyone has a phone?

They don't need to: they can read your mind. My proof? Yesterday I was driving home and I saw an old Toyota Previa minivan and thought to myself "Oh, a Previa, you don't see those very often these days." When I got home, I started scrolling through my Google News and it showed me an advert for the new Previa. I agree with Simon: you basically aren't going to convince someone that their phone doesn't listen to you and…

I think people are prone to believing that their phone is listening to them out of an instinct to believe they are a lot more unique than they actually are. A clash between western individualism and hyper-efficient consumerism.

That's not me taking a stance on whether it's true, though. There would be a lot of fame in it for a whistleblower, but on the other hand if Google or Meta figured out a way to do it with a low chance of it being proven, why wouldn't they?

This is due to ad blindness.

The Previa ads were always there but that was the first time you noticed it because it was on your mind.

I have similar anecdotes about this and Yamaha guitars.

I had this happen to me recently. I was speaking to a friend about a subject that suddenly started to appear in ads after I hung up. It was spooky. But I think it has more to do with the activities related to the people we know. I'm sure because of Android, Gmail and search they have a good understanding of our general association group. I bet my friend did a search on what we were talking about and Google was able to determine that others in the group would be interested in the subject. They don't need the microphone input. They have better (more direct?) ways to get the information.

Now tell it over a campfire and maybe shine a flashlight under your face.

The party told you to recount the evidence of your eyes and ears as a campfire ghost story. It was their final, most essential command.
