In the 20th century, there were two spaces after an end of sentence period. (I still do that.)

Only if you used a typewriter. I was using (La)TeX in the twentieth (1990s), and it defaulted to a rough equivalent of 1.5 spaces (see \spacefactor).

Two ('full') space characters were added because of (tele)typewriters and their fixed width fonts, and this was generally not used in 'properly' published works with proportional typefaces; see CMoS:

Good to know! I am reminded of using *roff in the 1980s. Punctuation such as periods at the end of lines marked end of sentences, and nroff would insert two spaces in that case.

  In HN, you can force two spaces between
  sentences.  But only in code blocks.

vim still does it, when joining lines.

Because I learned to type on a typewriter, I always ended every sentence with a period and two spaces. But LaTeX was kind enough to not care whether I put one or two spaces, and gave me the right proportional spacing regardless.

Thanks for sharing. I'm a double spacer, but have to agree it does look to wide most of the time, while single-spacing looks too narrow. 1.5 sounds like a greatGoldilocks spacing. I only wish it were easier to use.

Very annoying how HTML changes your two spaces into one space.

I use “ ” if I really need a blank space.

When I was growing up (90s), we were taught that either one or two spaces was acceptable practice.

I was thought two spaces was for fixed width (typewriters), whereas one space was for word processors with proportional typesetting.

Indeed, Emacs has historically used the double space at the end of a sentence to provide movement and cut functions operating on sentences.

I think Google Docs does this automatically.

I've been called out on this by coworkers in code review. It's mildly infuriating.

These are the moments that I need to have a confrontation about not bringing up unimportant things. The person who wrote the comment intended to communicate things about the code. The person who brought up the punctuation could change if if they really wanted to, if it was actually productive work. It's about "catching" someone else and having a reason to nip them on the ear. Review like that is what belongs in the garbage.

I keep punctuating like it's the 18th Century, myself;—compound points are my favorites:—like the colon-dash compound, AKA the "dog's bollocks."

People whose ideas get heavily criticized for "being written by AI" (with most readers missing the point) have less influence and perhaps that influence matters enough to them to adapt, i.e. to "let others change them"

Exactly my thought upon seeing this :)

I agree. Reminds me of a few years back, when I got a Red Hat baseball cap which is (obviously) red. I had people telling me "oh no you can't wear that, MAGA hats ruined that". To which I say, balderdash and poppycock. I refuse to let others' mistaken assumptions dictate my behavior. If someone sees me wearing a RHEL hat and hates me because they assume I'm a Trump supporter, that's their problem, not mine.
