Can’t nvidia and the papers authors sue you or claim a takedown / charge licensing or something ?!? How is it legal for people to take cutting edge tech from universities for free and use it for their own software/profit?

same as it’s legal to use open source licensed software to profit. a lot of academics don’t care, and their work might be built very strongly on other work. there might or might not be a patent on this research, but I would guess probably not?

I thought github projects were only ok to use if the author provided a LICENSE file e.g. MIT or APACHE 2.0 , do these papers include a license clause at the bottom? Usually no right , so it seems to be a ‘grey’ area

I'm worried about the social ramifications and moving us one step closer to "post-truth". Not much we can to do stop it at some point, but if a certain pee tape came out in the next year, there'd always be a reasonable doubt to its veracity.

(they're almost taking credit for Pytorch as well). Sure, this kind of work wouldn't be possible…

It's a company blog. It exists to highlight applications of the company's products. I don't see why you are bothered, both of those statements are factually true.

Yeah, I don't think people are lending enough weight to how big of a deal that is.

We're heading into a world where it would not be very hard to bombard the public with a large number of long form videos of highly convincing videos of anyone in the world ranting on any topic and acting out anything they want, and we would have borderline no idea if it was legitimate.

Combining that with our media climate and already runaway problem with monetary and political incentives for fabricated stories seems really dangerous.

You could make a video of Neil Armstrong and Nasa execs talking about how they faked the moonlanding, or even much more nefarious fake content confirming conspiracy theories for political ends.

What will we use as a scalable filter to know what is actually going on, and how will we keep that content from manipulating public discussion?

I'm sure that this will, at no point, be used for evil.

Indeed. It's still in the uncanny valley, but then evil is uncanny valley too. Goodness has always been linked in our minds with beauty and grace, including grace of movement.

Oh man, the first company to put this in a mobile app is going to blow up. (I guess it might take a few years for the performance to get there)

Isn’t there a patent / copyright or something for taking all the algorithms / structures in the tech stack that this relies on? (GAN , densePOSE , etc) Is any tech that is published in arxiv just free game immediately? Seems unfair to the researchers

It's their choice to publish.

Wouldn't the solution to that be to render in the cloud?

Then your problem becomes 'How to you monetize an app that costs us $20 in GPU cloud time every time someone taps a button'

Reminds me of deepart.io...

They started with a single GPU. As the waiting queue was getting longer, they made a paid feature that would let you get your results faster. Then they rented more GPUs with that money.

I could see this being used in the same way that auto-tune type effects are added to singers voices. The editing of music videos could include a tool like this to make sure all of the dancers behind the main one are moving just right. And just like auto-tuned voices, it will come off as janky and fake.

It is still noticeable in normal performances. You can hear unnatural overtones from autotune used as intended. Even more so when supposed singers use it live and have to stay glued to their mic to isolate any outside noise.

Interesting! Do you have examples where it is possible to hear these unnatural overtones?

It's easier to hear in modern country music because the vocals are still trying to sound natural. Male singers are more obvious.

Funnily enough, I think this technology would be better demoed by people doing more natural motions like walking around and doing basic gestures, or dancing in a style that is more fluid. This type of dancing is made to look intentionally "unnatural" (ie: you rarely see people moving like this in your daily life), which makes it a bit difficult to tell how much of the strangeness/unanny-ness comes from the dancing style vs imprecision in the algorithm.
