Dude doesn’t even know about the magic smoke.

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.

They didn’t start it with rocks. The first calculators used gears. Those were hard to reprogram. So they started using relais. That worked but was very slow. Then they found out that lamps (vacuum tubes) could take the place of relais but these wore down too fast. Then someone figured out that rock stuff (silicium) could do the same as a vacuum tube. After that it became a race to make them as small as possible to cram more of them together.
