An underappreciated force behind great technological change is intense—and petty—rivalry. In the “war of the currents” in the late 19th century, Thomas Edison electrocuted stray animals to discredit Nikola Tesla. A century later Steve Jobs traded insults with Bill Gates during a battle between Apple and Microsoft. Even “Silicon Valley,” a satirical HBO series, starts with a feud—and the priceless quip: “These are billionaires, Richard. Humiliating each other is worth more to them than we will make in a lifetime.”
