Before I get deeper into this argument, the main point I was trying to make is that people are clearly assuming based on the headline that the transcript analysis happens in the cloud, and aren't aware of them at least claiming that it's fully on-device. If Google wants to steal phone transcripts, they can do this already, this feature doesn't change anything about it.

Also even if they wouldnt collect the data, its a fucking horrible idea in the first place. Sure lets outsource trust to an algorithm that is dumber than a fucking toddler.

The privacy discussion aside, the feature is designed to step in and warn the user when it detects a likely scam in progress. I don't see how this is inherently a bad idea at all. My grandma got scammed on the phone hardcore a few years back — this likely would've prevented it. And "outsourcing trust to an algorithm" is clearly not what's happening here. People get scammed all the time, clearly more needs to be done to stop scams.

Other than this... I know that people especially here are super wary of google and their privacy-related claims for very good reason. I am too. I know this is a very sensitive topic. But realistically, for this particular discussion...

"Ofcourse they will gather all that data, because why wouldnt they?"

There are so, SO many reasons why a massive company like Google, especially one that is constantly under scrutiny for their privacy practices, wouldn't secretly record / analyze / store / whatever private phone conversations and tbh most probably just aren't. There is immense regulation around this topic in practically all markets they operate in. If Google was found straight up sending transcripts of phone conversations to their servers without very explicit consent (aka more than some clause in ToS somewhere) it'd realistically be the biggest scandal in Google's history, and likely significantly hurt, if not kill, at least their phone division. In many markets just the recording of phone conversations is already illegal without consent from both sides, and Google can't just do it anyway based on some ToS legalese — it's just illegal.

I'm not trying to say that I don't believe they do this because they're good people or anything, but because from a pure business standpoint it'd be immensely risky for gathering data that is also hardly usable in practice due to how sensitive it is. The circle of people that would even be allowed to know of its existence internally would have to be tiny and extremely trusted to prevent leaks.

The truth is that they can amass so much data through other potentially dubious yet totally legal ways already, so an immense and illegal overstep of privacy convention like this is just unnecessary.

While I do agree with the premise of your comment, most countries (including the US) have strict and long-standing laws on recording phone conversations. Even if Google wanted to do this, I can see it being an absolute nightmare to egress data from a device onto external storage.

Of course they will gather all that data, because why wouldnt they?

But they promised...

Sure lets outsource trust in our communications to some shitty machine learning algorithm that is dumber than a fucking toddler.

And it really doesn't need to be smarter than that, to show a "banks will never asks you to transfer money to another account, this is likely a scam" dialog when the speaker claiming to be from your bank tells you to do so. This will save lots of vulnerable and older people from getting scammed. If you think that's a horrible idea then I'm interested in your reasoning. Over $10 billion per year is lost to scams, making a dent in that is amazing.

Actually from what I've seen Google has moved hard towards reducing gathered data and encouraging play store apps to use less permissions and data.
