Attempting An iPhone In 1957

Building an iPhone X equivalent in 1957 would have cost $150 trillion in today's dollars. And it would have been massive:

Consider the 256 GB memory iPhone X: Implemented in vacuum tubes in 1957, the transistors in an iPhoneX alone would have:

• taken up a hundred-story square building 300 meters high, and 3 kilometers long and wide
• drawn 150 terawatts of power—30 times the world's current generating capacity
