No, You Don't Want to Time Travel

“There is a joke about two economists hiking in the woods. They come across a pile of shit, and one says to the other, “I will pay you $100 to eat that.” The other economist eats it, gets the $100, and they keep walking.

Then they come across another pile. The second economist says, “Now I will pay you $100 to eat that pile.” So he pays the first economist $100 to eat it.

Afterward, they say, “Wait a second. We both ate a pile of shit, and we have no extra money. You just gave the $100 back to me, and we both ate shit. This does not make any sense.” - Elon Musk on Economists

No, You Don’t Want to Time Travel: Time travel is a very bad idea. Very, very bad. So, let’s say that you, being the genius that you are, have solved the physics problems of traveling through time. You have invented and built a time machine and are eager to use it. Sounds great, yes? Even if time is the fourth dimension, you cannot forget about the first three dimensions. Moving through time also means moving through space. Let me explain.

Why Most Stock Traders Will Continue to Lose Money, Explained through Math: Wall Street’s most profitable firms are not doing something cleverer than a casino. They are doing the same thing, with the same four moving parts. The four gears are: Edge, Volume, Sizing, and Bankroll. The casino has all four. The best funds have all four... Imagine two players flipping a fair coin for a dollar a flip. Truly fair, no edge to anyone. One player has 10 dollars, the other has 1,000. They play until someone is broke. Who goes bust? The math is merciless and clear: the player with 10 dollars is almost certainly the one who ends up with nothing.

The Phoney Fanboys of Christopher Nolan: You may say that he is famous because he’s very good, but he is not the only one who is good, yet his fame is singular. Probably no one has been quite as revered, even at his peak, not even Steven Spielberg or James Cameron or Quentin Tarantino. Much of Nolan’s success comes from a combination of special factors—an early break, when he was not a threat to influential figures and they could be generous to him; the narcissism of cults; the transmission of his myth through the misunderstanding of fans who projected their own ideas onto his films; the frenzied word of mouth among those who are new to a cult; and the dreariness of his high budget works that gave them gravitas.
