@ireneista that's becaude when vi was made, a terminal @ 9600/8/N/1 was considered 'extremely fast' and any redraw on 80x25 with 9600bps is still very clearly visible…

• So you can imagine how painfully slow a 1200bps VT-100 or even 300bps VT-52 must've felt back in the days.

Like in 1976 being screen-oriented was the new hotness, because most systems still used teletypes exclusively (that's why #serial console got their name prefix tty and program from) and so changes could be more interactive on a terminal compared to ed
