Yes, you're right, LEGO is extremely uniform, and no real system is _that_ uniform.

And even a uniform interface doesn't mean any combination makes sense.

Attaching a LEGO brick with wheels on the roof of a LEGO car is not different than soldering an axle on the roof of a car: technically possible but utterly useless.

Actually, soldering an axle on the roof of a car is composing uniform interfaces: atoms in chemical bonds form a finite set of building blocks too!
