Go watch some videos of Kern machines. Their demonstrations of drilling through human hairs with a VMC are pretty compelling.
it might be better to say that machine components and coordinate measuring systems have become cheaper, so that high accuracy is more attainable.
Good machines 50 years ago could hold .001" tolerances with care. Most machines nowadays can do that without that much care. Some machines nowadays can hold .0001" tolerances with care, and some can do even better.
