A nitpick: You are greatly underestimating the precision in gravitational-wave astronomy.
ASML's atomic scale corrections are approximately one billion times larger than the fraction-of-a-proton's width displacements measured by LIGO.
From https://www.ligo.caltech.edu/page/facts:
> At its most sensitive state, LIGO will be able to detect a change in distance between its mirrors 1/10,000th the width of a proton! This is equivalent to measuring the distance to the nearest star (some 4.2 light years away) to an accuracy smaller than the width of a human hair.

That's insane! Thanks for sharing

I was wondering how much farther down they could theoretically go :
Typical Si-Si bond length is actually only 0.24 nm !
ASML has plans to get into sub 1nm level. 2nm and 1.5 nm is already in the pipeline.
The technology high-NA EUV (high Numerical Aperture Extreme Ultraviolet) becomes just insane. Mirror manufacturing process requires atomic scale corrections and the whole metrology is moved into vacuum.
The limit for mass production is measuring and calibration. The measurement accuracy is comparable or exeeding Large Hadron Collideror gravitational-wave astronomy. The speed (wafers per hour) must eventually slow down, requiring more machines and making the process more expensive. Then Moore's law finally dies due to the cost.
