Yes. It's important to remember that we've already lost connectors from < 100 years ago. Now USB-A does have a lot more mass production and popularity for it today which does have something going for it. But remember that changeovers happen quickly and 200 years is enough time that anyone who cares about the legacy dies and there's no market to sustain the adapters. 200 years from now you'd expect all physical connectors to have disappeared with wireless variants taking their place.
