They taught me in high school to double tap the spacebar after a
sentence. That was 1996. No mention of one space that I recall.
Almost nobody was using type writers at that point.
At least they taught me to type and I'm glad for it. I have a colleague
who hunts and pecks with two fingers on each hand. This guy has a
masters degree from Harvard, so whenever I see him type I marvel at the
thought that he must have jammed out a 20 page thesis by hunting and
pecking.
For me it's quite literally a tell for how old someone is: before or
after typewriters. When we were taught typing in middle school it was
using computers and it was single space. I was *told* that on
typewriters it was two spaces.
