Put it to memory

Looking for some RAM on Amazon I was astonished to see that memory has doubled in price since 2016. That set me on a inter web journey: first to try and discover why; then to have a look how CPUs are made; then to see how CPUs work (still don’t know); then to watch something about quantum chips (dual states, up spin and down spin etc) and finally lots of stuff about the universe, interglacial periods, black holes, white holes and... That’s my evening done.
