I couldn't find the comment again, but as somebody else said here on HN a while ago. The comment was like ..

We live in special times. Until 100 years ago we had just news from other people, mouth to mouth. So we had to decide what is wright and what just BS. Last 100 years we had newspapers, radio and TV. News was mostly true, we could trust what we saw on pictures, on screen. But now again .. pictures can so easy be just fake. So we have to decide again, what is true and what BS:

I'm old enough to remember back in 2005 when terrorist in Iraq claimed to be holding a US soldier hostage, and it turned out the whole thing was staged using photos of a doll: Original story: https://www.nytimes.com/2005/02/02/world/africa/rebels-say-t... Confirmation of hoax: https://www.nbcnews.com/id/wbna6894934 It's pretty easy to see that the photo is a hoax, but many news outlets didn't notice and ran the story…

They ran the story as a claim that a US soldier was taken hostage, not as a fact that a US soldier was taken hostage. From the NYT article:

"The authenticity of the militants' claim Tuesday could not be immediately verified. Defense officials at the Pentagon in Washington said that the U.S. military was investigating the incident but that had no indication any of its soldiers were missing in Iraq."

You have one of the scariest HN bios I have ever read.

I’d say it’s either a joke, real, or a canary.

Betting on all possible outcomes doesn't really make a statement...

Entities like CFOs and political leaders will have to start cryptographically signing their statements. There is no practical way to detect fakes after the fact.

I honestly find it suprising that photo's and video's taken with a smart phone are not signed in some way to ensure they are not modified.. Would love to see it become more mainstream, since editing is so easy.

A recently announced breach at Retool[0] involved the use of a deepfake version of an IT employee's voice for social engineering. [0] https://news.ycombinator.com/item?id=37500895

I must admit I found that element of the story...surprising. Has realtime faking gotten that good yet? Presumably there was back and forth in this call so this person was either disguising their voice or typing responses to be generated on the fly. I know all this can be done, I'm just surprised it's reached the maturity where an attacker would choose to impersonate someone the call recipient presumably knew vs just…

You could probably reduce the "delay" by using a soundboard of pre-generated filler material and playing that while you type the real response. "Let me find that bookmark", "So the thing about that is...", "ummm yeah. so...", "hmmm no not really"

You can also use text macros to type the response faster. Here they were trying to get MFA access, so you could map longer phrases that will come up often like "Okta multi factor authentication" to numpad 1. Company name to numpad 2. IT supervisor name to numpad 3.

If you know the target of the conversation you can tailor what you pre generate. I like to mess with scam callers when I get one, and I've noticed some are using some kind of soundboard with a woman's voice (I'm pretty positive it is real and not AI) and they have a planned flow / script. If you try to deviate from the script they have some options to bring you back into it. If you ask them to repeat something you can notice it's the exact same audio snippet as before. If you accuse them of being a bot they have a few samples of the woman being shocked and mildly embarrassed. "Oh my goodness, do I really sound like a bot? No it's just been a long work day for me. I'm sorry about that."

It might bring down all the bridges the internet helped build. Also, it will make the world more centralized, having to trust more on big names and institutions. As a libertarian, this is the opposite direction I’d like the world to go in.

We need to start trusting people we know again. Not institutions or celebrities on pedestals. We need to trust our family and friends and community again.

It's interesting that you've gotten so many downvotes. The sad thing is that as things are progressing in the west, a large number of people won't have families or communities to lean on.

Reliably left wing? Yes. Reliably truthful? No.

Please link me a single story you think NPR was untruthful about.

NPR dutifully ran the "Saddam Weapons of Mass Destruction" *fake* 100s of times with utter sincerity.

ps- also the "dumping babies on the ground" fake too IIR, but maybe only a few times on that one. Congressional testimony on camera by a daughter of a State Department official IIR to justify the Kuwait invasion by Bush I

100 years ago was the time of yellow journalism, where lies were commonplace.

Almost every issue on the 2A they discuss is untruthful. The Rittenhouse case comes to mind immediately where they lied about all the encounters that were proven wrong in court. They avoid anything that makes the left look bad. Lying by omission is still lying. They continuously link stories to racism, lgqbtq, "people of color" that have nothing to do with any of that as well.

Keep listening to them if you want. I used to be an avid listener, just realize that they've lost a TON of loyal listeners due to their heavily biased reporting in the last few years.

Here's a fun one for ya. They backtracked on it after not getting away with it but there are many many more where no one notices and they just get away with it.
