Two spaces pre-dates the computer world of course. I remember taking typing lessons on a manual typewriter while in high school (50 years ago). We were taught to hit the space bar twice after a sentence. Of course, there was no choice of font, no proportional spacing, and if you hit the wrong key you pulled out the piece of paper (and real carbon paper if you were making a cc) and started again.
No, I don't look upon that era as "the good old days." but I'm perfectly content for TeX to handle the end of a sentence and to manually insert a hard space if it gets it wrong.
