This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.
Be warned:
- Anon is often crazy.
- Anon is often depressed.
- Anon frequently shares thoughts that are immature, offensive, or incomprehensible.
If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

When I learned about how they are making the new CPUs it blew my mind. Dropping a microscopic droplet of metal and blasting it with lasers to a stencil like thingy to create the nanometer circuitry. I was like how the fuck did you even thought about doing that?.. Technologies like these are really marvelous.
You start with macroscopic photolithography, add material science of semiconductors and then iterate a million times. It didn't start at nanoscale.
Exactly, and “we need this as small and precise as possible” means “can lasers do it?” As an engineer I default to fast and precise means computer guided laser if possible
They use electron beams and extreme UV light nowadays. Lasers are not necessarily the best light source, even at other wavelengths.
