If you look at the statistics, you’ll find that casual, condomless sex is very common. Despite the risks of STI transmission, it often pans out okay: most STIs are readily curable, while HIV has a low transmission rate amongst heterosexual couples (about 0.08% to 0.2% per sexual act) while PrEP is pretty common for homosexual men, and HSV has fairly low odds of transmission outside of an active outbreak (annual odds of transmission amongst couples: about 11–17% for couples with a male source partner and 3–4% with a female partner). Consequently, many people who have casual, condomless sex with many, many partners will end up just fine.
Is it reckless? Well, the connotation of “reckless” is fairly negative, and I don’t see why I should get to judge what two consenting adults decide is an acceptable risk vs reward for themselves (at least, so long as I’m not involved).
However, when we pivot back to the domain of software/engineering: when software design choices are made via bandwagon fallacy, claiming that “it usually works out okay”, I do find that to be reckless. You may be fine with such a carefree approach, but it isn’t really fair to other engineers, users, and stake holders.
It’s not that I believe JSON (or similarly pitfall-laden technology) should be strictly avoided, but rather that the risks and failure modes should be given serious consideration, rather than minimized or outright dismissed. In terms of the STI analogy, it’s perfectly reasonable for two individuals to be aware of the risks, and depending on their appetite for said risk, agree upon the inclusive/exclusive nature of their relationship, as well as whether they exchange test results; what would be ridiculous is to pretend that the risk of infection is zero.
There would be zero value in the article minimizing the design flaws (and resulting footguns) in JSON. The insistence that the article should do so is about as bizarre as someone responding to an article on safer sex by insisting that the article be amended with a note that “… but raw-dogging strangers isn’t too risky anyway, so, like, YOLO”.
