For almost four years, the university at which I work has tried to
automate the doors at the main entrance, such that they swing open
when a visitor goes near. For all of that time, I don't think I have
ever seen all doors being operational on any given day. At least one
was always broken (and sometimes all of them were), and even when they
did work, they opened very slowly. I suspect much of the damage was
due to impatient visitors who simply pulled them open so they could
get in. (I certainly did that a few times.) It got to the point where
they actually started putting up signs indicating which doors were
operational on any given today.

Well, apparently the university finally gave up on this fancy
automated door technology! They are back to being manually operated.
No longer will I have to be frustrated every day by something as basic
as a door not working. (The powers that be had taken off the door
handles, so when the automation did not work, you could not open it
yourself.)

I will never understood what this multi-year project hoped to
accomplish. One the doors was already automated to enable access by
people with limited mobility, and because it was used relatively
rarely (it is off-center), I think it rarely broke.

Well, anyway. Once the fancy quantum computing research project has
solved the problem of quantum computation, maybe they can turn their
talents towards the apparently still-unsolved problem of automated
doors. Although to be honest, I don't really need it.
