Well I can see resistors, capacitors and inductors as fundamental but when you beyond that I'm not convinced that a resistor with hysteresis is particularly more fundamental than an inductor with hysteresis (as in core memory) or a capacitor with hysteresis (not sure they've invented that yet) or a diode for that matter. The "we've discovered the forth fundamental component" stuff seems a little like hype to me. Not to knock its potential value for building computers.
