Please don't be snarky or cross into putdowns or personal attack. We're all in (let's call it) the unlucky 10,000 about something. About most things actually.
To an extent that's fair, but you do understand that "ive not heard of a vulnerability older than me" begs credulity? Especially with the fifteen years experience comment? I'm all for not being snarky (I'm not), but this was bait
I can understand why it had that effect on you but these are effects it's necessary to resist. From https://news.ycombinator.com/newsguidelines.html, for example: "Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."
There is an interesting episode of This American Life about how everyone, everyone, has weird gaps in their knowledge that eventually get filled in sometimes fun or humiliating ways. You have these too.
Wow, what is that episode? I haven't listened to TAL in probably more than a decade but it was great for a long time, and for all I know still is.
"A Little Bit of Knowledge"
I can see that you're old and that I'm older, but I fail to see the justification for being snarky about that.
Please don't sneer, including at the rest of the community.
