Depends on how deep you're willing to go to really, You need one of a few arrangements of flip flop circuits to keep 1-bit state. Going deeper, you need either NAND, or NOR gates(or a bunch of other ones) and connectors. Even deeper, you'll require diodes or transistors to build the logic gates. Beyond that is particle physics.
A disruptive technology sweeps away the systems or habits it replaces because it has attributes that are recognizably superior. Recent disruptive technology examples include e-commerce, online news sites, ride-sharing apps, and GPS systems.
