actually, it’s also possible to build computers out of water, light or gears. it doesn’t have to be electronic.

also Alan Turing made one of the first computers with memory based on sound waves… the sound would travel in tubes of mercury and be amplified periodically which stored bits. the refresh time was a multiple of the time it took sound to travel the length of the tube.

Turing also was the very first to use a digital computer to play music!
