There's utility in promptly admitting when we're wrong.
I didn't waste anyone's time. They were more than happy to ding me. In fact, there's few things that geeks like doing, more than telling other geeks, they are wrong, so I maybe did a public service.
I'll do humor, and, if people want to get butthurt, they'll bang on the down button, just like they always have.
(Unless I was wrong to read "I don't know why people are downvoting my mea culpa" into this comment - https://news.ycombinator.com/item?id=40961512 - but I can't think what other meaning it could have in the context of replying to your own comment which had been downvoted).
Regardless, I won't bother coming back to this thread as I've wasted enough time myself by choosing to comment to not care further.
