Quip
It took 300 years to build and by the time it was 10% built, everyone
knew it would be a total disaster. But by then the investment was so big
they felt compelled to go on. Since its completion, it has cost a
fortune to maintain and is still in danger of collapsing. There are at
present no plans to replace it, since it was never really needed in the
first place. I expect every installation has its own pet software which
is analogous to the above.
