This reminds me of the story set in ~1900, when the gray-beard physicist tells his student not to study physics because all the big questions have been answered, and physics as a science will end in a few years.
Which also reminds me of a comment I just read about the singularity coming within 20 years. It just shows us how limited and distorted our vision of the future of science truly is.
They made a simulation which matches reality pretty well, but they worked backwards: they knew the value they wanted and kept tweaking the simulation till it worked.
That's not quite as exciting as being able to calculate it from first principles.
