But here’s the catch: Most of the time, we do almost nothing. Our most common tasks—email, Web surfing, watching streamed videos—require very little processing power. Only a few people, like graphic designers and hardcore gamers, actually need heavy-duty hardware. For years now, without anyone really noticing, the PC industry has functioned like a car company selling SUVs: It pushed absurdly powerful machines because the profit margins were high, while customers lapped up the fantasy that they could go off-roading, even though they never did. So coders took advantage of that surplus power to write ever-bulkier applications and operating systems.
Bingo.
