With 1 #transistor, I can make an inverter, a switch, or a not-very-good amplifier.

With 2 transistors, I can make a differential amplifier, a cascode, or a latch.

With 3 transistors, I can make a fairly good (Wilson) current mirror, or a Lorenz chaotic system.

20,000 transistors made a #computer that navigated spacecraft to the Moon and back.

But 10,000,000,000 transistors make a computer that's brought to its knees if it tries to interpret the Javascript used to load one #ad on a web page.
