My, my, TTY!
summary
Claims that the TTY abstraction is ancient yet still drives modern shells, demonstrated with concrete milestones: PDP-7 UNIX is built in 1969 and works, terminals evolve from paper Teletypes to ADM3 to VT100 80x24 and VT220, libraries appear (termcap then curses) with database growth termcap 22→50→1700, multiplexers and emulators appear (screen, PuTTY), and networks harden as ssh replaces telnet 1995 so the virtualized Teletype survives and shapes software design.
