the author of the article wrote an article a while ago about how they think steam is enshittifying and becoming bad because they got rid of mac support and some people didn’t like steam in the 2000s, so I think this person just takes controversial opinions randomly and writes about them.
lots of fun techniques, a common one for getting down low enough where other methods become practical is stirling cryocoolers, and those are even on ebay for a few thousand (cascade refrigeration systems, and joule thompson coolers, and a few others are also used), way down past that theres stuff like weird magnetic coolers, and dilution coolers All very interesting, reading about exotic cooling methods is quite fun.
