Also, tty is relatively space inefficient, specially on modern "high
res" monitors where many xterms can be layed out to provide an
efficient workspace - yet X (poor security) or Wayland (better?) is
required to make use of all those columns and rows, and probably few
these days would live without some GUI programs (browser, word
processor, video/ tube viewer).
When bitbanging your tty subsystem pretty well guarantees lockup, we
can say we've a long way to go for robust "secure" systems …
notwithstanding the hardware issues so visible today.
