For English to German I don’t need machine translations, but yes: English to German translations are even more catastrophic. I sometimes translate from Polish. But I also tried some other languages … None of them produced results I’d consider good by modern standards.
Translating something to English is slightly better, but if THIS is the best we can have right now, then the best we can have right now isn’t even close to what we COULD have right now (with the right training data and resources).
I expect there’s a project you can join
I did a quick research that took longer than I wanted it to take, and the Mozilla Corporation is really good in hiding anything even remotely related to how the translations work and what the community can do.
