I had a European peasant in the 1600-1700s in mind when I wrote about the amount of work. During the season, they worked all day; off-season, they had "free time" that went into taking care of the household, inventory, etc., so it's still work. Can't quickly find a reliable source in English I could link, so I can be wrong here.
"Better" was referring to what OP wrote in the top comment. I guess 10x faster, 10x longer context, and 100x less prone to hallucinations would make a good "10k x better" than GPT-4.
