Russian version of this article, published slightly earlier AFAIU ( https://habr.com/ru/companies/pt/articles/863536/ ) does not look very AI-assisted, but still contains some of the weird moments you mentioned.
"discreet" looks like translation error, in russian version word "special" is used. PC/AT is still there, as well as Xeon example (latter does not seem "not quite right" to me)
