One of the saddest things that has happened in modern times is that almost everything you ask your computer to do is done instantly.
Now most people will tell you that's a great thing, but I'm here to tell you that I remember the days when I would start a program compiling and go off to have dinner while it worked. Those were the days.
There is nothing quite like knowing your computer friend is hard as work on something while you go take a nap or grab a bite to eat.
That's always been one of the appeals of doing scientific work on the computer -- I once ran a program on my pc that took 2 months to run and it was an unadulterated pleasure.
Progress bars are just the icing on the cake
