Honestly, the article needs to be replaced with https://deepmind.com/blog/article/AlphaStar-Grandmaster-leve... which actually goes into some technical detail. Nature.com's article is purely for laypersons and, imo, not particularly useful for HN's crowd because of how little insight it gives.

It also provides the paper and an archive of all of the AI's matches for anybody who wants to take a closer look. These can be viewed with the free version of SC2 (afaik).
