 We are Living in an Ancestor Simulation

Now we get to the core of the simulation argument. This does not purport to demonstrate that you are in a simulation. Instead, it shows that we should accept as true at least one of the following three propositions: (1) The chances that a species at our current level of development can avoid going extinct before becoming technologically mature is negligibly small (2) Almost no technologically mature civilisations are interested in running computer simulations of minds like ours (3) You are...

 Computer Simulations Allow for Mistakes

. . in real life mistakes are likely to be irrevocable. Computer simulation, however, makes it economically practical to make mistakes on purpose. If you are astute, therefore, you can leam much more than they cost. Further¬ more, if you are at all discreet, no one but you need ever know you made a mistake.

 Common Core Math Standards

Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem ...
