A single computer transistor now costs one millionth of a cent

In 1970, a single transistor—the tiny switch that allows a computer to think—cost about one dollar. Today, that same piece of technology has plummeted in price by over 99.9 percent. This collapse in cost is what allows companies like SK Hynix to stack twelve layers of ultra-fast memory into a single chip, creating enough digital bandwidth to process 1.2 terabytes of data every second.
