Eli5: How is it possible that advancement in USB allows us to transfer larger data in faster speed, yet the diameter of the wire does not change.
In: 17
Just realise that we’re much better at cutting time into little pieces than cutting space into little pieces. So instead of adding more wires, we use the same wires but with more data per piece of time.
As an aside, you can make wires *too* small, such that electrons can actually fly out the corners. There probably limits to how fast you can flip bits, but we’re not there yet.
