That last word should be not WERE but, ARE. They still are used.

They were not always thought of as computers, hence the neglect. Think
servo
systems and they come back as those very non digital systems. They may
have been part of a larger mixed system like a attitude control system in
a
missle or autopilot for an airplane. The systems encompassed in the
analog
computers are around us still.
