Normally we would treat these as duplicates, but Grothendieck is exceptional.

(Actually, what we normally would have done is disallow the French-language article—not because the French language isn't magnificent, but because HN is an English-language site. But Grothendieck is exceptional, and it was likely going to take a day for a high-quality English piece to appear.)

I appreciate the link, and that article has much good discussion. I would not exactly call it a "duplicate", though: it is in French and this article is in English. I think both threads are valuable.
