What was the concern about typing too fast? That the mom couldn’t monitor what they’re typing because they were submitting before she could finish reading?
Twelve year old me learned to type fast from flaming my opponents during StarCraft: Brood War public 1:1 Lost Temple matches.
Gotta type the message and send as quick as possible: those SCVs ain’t gonna start mining minerals or vespene gas on their own; supply depots won’t build themselves.
I was about to disagree, but I realized that 12 year olds typing fast is probably even more rare now than it was when I was 12. Let's just say, in the days of dialup lol ;) At the time, I typed faster than anyone I knew, other than a couple computer-geek friends who also spent hours chatting online etc.
My 14 year old types faster than most adults. And has been able to do so for a couple of years. She wanted the skill for the game One Hour, One Life and there are free typing apps out there.
I was about 9 or 10 years old when this moment happened mind you, I was typing with two fingers, one on each hand, nowadays I use at least three or four fingers per hand to type, which is a lot faster.
When I was 9, we had a typing class at school and I learned to touch type (i.e., 10 fingers) at about 20 wpm. By 12 I was up to 40 or more. I suppose I would have been blocked.
