Was wondering about that too. It certainly produces realistic-looking high-res images, but especially when the article talks about potential uses ranging "from restoring old family photos to improving medical imaging", it seems like accuracy may be more valued than "looking realistic".
- jeffparsons 5y ago> improving medical imaging Spot on. This is not "zoom, enhance" — it is "fabricate plausible detail based on a training set". Using it for anything other than making pictures look nice would be disastrous. Other people in these comments are talking about using it for law enforcement. Train it on a bunch of pictures of black people holding guns and now suddenly it will "reveal" guns in the hands of all black people in blurry CCTV footage. (This specific example is likely a little simplistic to be a problem in reality, but it demonstrates the problem of thinking it actually reveals some hidden detail.)
