sex testing isn't making people discover that they're intersex, it's making people intersex. if someone's sex characteristics are imperceptibly different to what sex defines they should have, it wouldn't have placed them in a different social category until both the technology and the drive to test were there. ppl just don't really believe that sex categories are also socially constructed and fluid. things like hormone levels naturally wildly range between people before it gets to a point where someone looks noticeably "different" for their sex—a cafab person with testosterone levels deemed high today would not have been intersex 200 years ago unless they displayed noticeably masculinised features, because nobody would have known anyone's testosterone levels and therefore can't use that as a basis for treating someone differently!
