Using “AI” has been beneficial for example to generate image descriptions automatically, which were then used as alternative text on a website. This increased accessibility AND users were able to use full text search on these descriptions to find images faster. Same goes for stuff like classification of images, video and audio. I know of some applications in agriculture where object detection and classification etc. is used to optimize the usage of fertilizer and pesticides reducing costs and reducing environmental impact they cause. There are ofcourse many more examples like these but the point should be clear.
I don’t think that is even necessary. If you download the .torrent file from a trusted source it will already contain a secure hash of the final file. Also every piece you receive also comes with a hash that can also be verified through the .torrent file. If you don’t trust the source enough to provide a valid .torrent, I don’t see how downloading the image directly from them makes any difference.
