How can plugs (such as USB) become smaller all the time, but also faster?

Question

I would expect more connections for it to become faster, so bigger plugs. But instead USB-C are much smaller than original USB (and SATA is much smaller than PATA, etc).

Even thought they’re small in size. They still have quite a few pins that it uses to transmit the digital signal. They run quite a pairs of channels.
