Mindblowing to see the staggeringly high tower of tech upon which modern chips are build. Machines capable of nanometer-precision movements at speeds subjecting their parts to 7G of acceleration... 25KW lasergun pew-pewing tin droplets 50k times per second... The sheer complexity of modern chip designs...

It really evokes Douglas Adams' quip that "Any sufficiently advanced technology is indistinguishable from magic."
