In your settings, you can set your preferred languages - since you're on lemmy.world this link should take you there. You can hold control down to select multiple options if you're on desktop (and mobile should have a selection box pop up).
Though be sure to keep "undetermined" enabled, otherwise a lot of stuff will vanish. Also note that this only works for posts/comments where people have actually selected the correct language (if someone posts something in German, but marks it as English for example, it will still pop up).
It'll still be tricky to translate memes since those words are often baked into the image. Unless they are doing ocr then overlaying the result, we'll need to hope someone transcribed the meme.
Thats actually coming aswel. Ai like chatgpt and google bard are gething their visual modules to understand images and text. A few demos have demonstrated the ability to understand memes in context.
We don’t need to overlay perse, Ive seen a few comment section bots already that explained what was in an image for blind internet users. As long as they are properly labeled as ai i welcome any ai interpretors that can aid global communication.
Yes. In your desktop settings, hold ctrl and click on every language you want to see. It's best to keep undetermined because some people don't tag what language their content is in. What you're probably seeing are these untagged posts, because I think registering your account asks which languages you want to see in the first place.
