NFT is just a token that represents the artwork.
You can screenshot, delete the original file or whatever but the token still exists.
Now the value of NFTs can be questioned, and the people who promotes them as well. We know for sure that some people will end up losing money when this fad ends so yeah giant scam indeed, but NFT as a thing still have use case, and you can say kinda the same about bitcoin.
I think is because they're going for a full machine learning approach, the neural network tries to learn the best solution but is unable to receive simple instructions like "go in a straight line"
