@hipsterelectron @sasha92 @mozilla There is billions of images online and an external human can't describe each picture that's missing alt text.
That project has a different goal than Mozilla's alt-text AI and I am sure you can use both - human descriptions with that project for the few images that will have it and Mozilla's AI for the rest.
@paper @sasha92 @mozilla you do know there are billions of humans right? wikipedia is widely used to train statistical models but it too is the compilation of many humans over time. adding alt text to an image takes about as much effort as editing a page (and often much less). do the math
