For me, one reason not to freak out about this is Photoshop. It's been around for decades. Perfect photographic fakes (literally called "photoshops") are possible. Yet is there a great crisis of fake photographs taking over the news? Not really. The actual "fake news" barely even bother with photoshop (and those for whom it works, don't care about the quality). It's somehow still fairly easy to get context and at som…

The other reason not to freak out about this is that we're already far down the path the people think deep fakes are creating. Reddit and Twitter and the internet prove that people will react to an image of text by the tens of thousands, going straight into their brain. All of us have been guilty of this at some point. To me it's naive to freak out about Photoshop and video deepfakes because it reveals that you're co…

The issue with deepfakes is this: at least in the other cases you outline, it's possible to be skeptical and weigh evidence-- including direct photographic and video evidence that is unlikely to be safe (while it may have been possible to fake before, it's been labor intensive and presents more risk that it'd have been messed up). In turn, we can evaluate the credibility of media sources based on how they agree with other evidence that we have directly evaluated.

As it becomes possible to fake more and more stuff, we're going to lose that. Different silos are going to have different, meticulously supported versions of the facts with an equivalent degree of direct-evidential and reputational support. And it's not clear to me as an individual one ever disentangles this.

Amazes me how people are okay with giving these massive corporations so much power and control over our lives - voluntarily. Most would be rightfully horrified if Walmart or Citibank was to decide what you get to watch or not tomorrow. But somehow, if Alphabet or Apple does it, it's all okay. The tech world in general needs to wake up about the overreaching power and influence tech companies have on our lives.

I can only imagine it's because what seems obvious to us is really not noticeable to 99% of people. You have to remember we are in a little bubble of our own for better or worse, most of HN readers principles are generally aligned against this kind of centralisation and we highlight and amplify anything we see that matches; I'm guessing your average FB user is more focused on the value proposition of these services t…

Much of it depends on the way people interact with businesses. Big Banks are bad because people can literally see overdraft fees and all sorts of surcharges being tacked onto their accounts, often in shady ways. Big Oil is bad because they literally pollute the environment and routinely spill millions of gallons of oil in the ocean.

In contrast, for the average person, Google is just the free little search engine that shows you all the answers and also gives you the free phone software. Whatever egregious privacy violations they do are wrapped up in a layer of abstraction that, if you don't get technology, can be hard to grasp.

The next generation is smarter though. They understand technology fundamentally and know that there's no such thing as "free".

The problem will increasingly be "whose algorithm do we believe". Internet has revealed that people believe mostly what they want to. We have seen that a large subset of people are believing Bill Gates is behind the pandemic. Why would masses somehow be more rational in picking the most rigorous and objective neural network to recognize deepfakes, than they are in making sense of the world in general? In the end we w…

Aren't digital signatures the best solution we have for this problem? Commercial entities want to have the priviledge of being able to modify the content submitted by content creators, but the culture of trusting i.e. Twitter over client verification needs to change.

Signing it doesn't mean it wasn't altered at some point and does nothing to actually verify the content - only if a source is who they say they are. And the key distribution is another issue.

That dumb meme about "big tech controlling your mind" ironically seems to be doing a far better job of what it accuses others. It has made people /unlearn/ how the internet and private property work.

Even with more egregious examples of moral wrong and stupidity like shutting down child molestation survivor support groups or just bad decisions like buying up Tumblr and trying to sanitize it weren't like but accepted as fundamentally how it works when it is their servers. There is no viable alternative to stop them from setting their rules. Even if they die there is nothing stopping them from taking their ball and going home.

Because YouTube, Facebook will flag these videos before they become too widespread.

You're missing a sarcasm mark. But seriously: at best it's going to be a big "maybe, it depends". These services bounce between PR disasters of "complicit purveyors of propaganda" and "oppressive algorithms destroying free speech", so you can't rely on them to be on either side. As deepfakes get better, the algorithms will have worse detection rate, so it'll end with Zuck testifying to congress that Facebook doesn't…

Perhaps the wild zigzag is a hint that the people casting accusations are utterly full of shit and just want them to bend the knee to their unpleasable whims?

Are deepfake face swaps a real problem yet? I can’t recall any major controversies in recent history that were caused by a deepfake face swap.

> This technique can be used to create compromising videos of virtually anyone, including celebrities, politicians, and corporate public figures.

I’ve read a lot of concerned comments like this but I haven’t read about any real world examples of a controversy caused by a deepfake.

This is getting stupid. People.. aging, cancer, Alzheimer's still exist. Maybe time to reprioritize & organize efforts?

Those are completely different deep specalties and best funded in parallel anyway given diminishing returns. Complaining about something that irrelevant to capabilities is like saying brain surgeons suck at inventing green energy.
