But seeing these trees through the lens of physics reveals even more beauty.”

In other words, consciousness is substrate-independent twice over!”

— Max Tegmark

20. “But why has our physical world revealed such extreme mathematical regularity that astronomy superhero Galileo Galilei proclaimed nature to be “a book written in the language of mathematics,” and Nobel Laureate Eugene Wigner stressed the “unreasonable effectiveness of mathematics in the physical sciences” as a mystery demanding an explanation?”

Roosevelt wanted to increase government spending, so he listened to John Maynard Keynes, whereas Ronald Reagan wanted to decrease government spending, so he listened to Milton Friedman.”

— Max Tegmark

— Max Tegmark

29. “It’s not our universe giving meaning to conscious beings, but conscious beings giving meaning to our universe.”

30. “The question of how to define life is notoriously controversial. Competing definitions abound, some of which include highly specific requirements such as being composed of cells, which might disqualify both future intelligent machines and extraterrestrial civilizations. Since we don’t want to limit our thinking about the future of life to the species we’ve encountered so far, let’s instead define life very broadly, simply as a process that can retain its complexity and replicate.”

— Max Tegmark

If you can hack and crash your enemy’s self-driving cars, auto-piloted planes, nuclear reactors, industrial robots, communication systems, financial systems and power grids, then you can effectively crash his economy and cripple his defenses. If you can hack some of his weapons systems as well, even better.”

— Max Tegmark

36. “The robot misconception is related to the myth that machines can’t control humans. Intelligence enables control: humans control tigers not because we’re stronger, but because we’re smarter.

— Max Tegmark

41. “Life 1.0”: life where both the hardware and software are evolved rather than designed. You and I, on the other hand, are examples of “Life 2.0”: life whose hardware is evolved, but whose software is largely designed. By your software, I mean all the algorithms and knowledge that you use to process the information from your senses and decide what to do – everything from the ability to recognize your friends when you see them to your ability to walk, read, write, calculate, sing and tell jokes.”

— Max Tegmark
