I've been quite taken with Go these last few months and I wish the western world had more skilled players. The Asian servers do not do much (if any) i18n, they don't need to, they aren't many players outside Asia.
I've been fortunate that one of my high school friends is a 4 dan EGF player and that he has taken lots of time to play with me and teach me. But I can see other beginners struggling with the basics because they're only playing other low-skilled players.
I wish the western world paid Go more attention, it's a beautiful game with a really nice balance.
Some things that may be of interest. First relevant to the posted article:
A site that has used neural nets to classify go moves that good players would probably make that weaker players (of varying ranks) would probably not: https://neuralnetgoproblems.com/ (code available on github)
https://ai-sensei.com/challenge (behind login wall, and in future possibly a pay wall) is a similar idea, but the difficulty of evaluating the position is determined by how users of the site perform in practice.
And more generally, but relevant to your comment:
Players can play humans at an appropriate rank on OGS https://online-go.com/ (not as popular as the Eastern servers, but probably popular enough) -- or against calibrated rank "human-like" AI players by painfully setting up the right katago models themselves, or by paying for a subscription on ai-sensei.com
A go education site that's currently largely by and pitched at Westerners: https://gomagic.org/ for leveling up from the basics.
And a lot of books are now available easily and electronically in English (and some in German): https://gobooks.com/ --- I'd recommend "graded go problems for beginners", "tesuji", and "attack and defense".
Some good sites aren't (fully) available in English, like https://www.101weiqi.com/ -- but there are chrome and firefox extensions to translate just enough of it to make it usable.
