A Python implementation of David Deutsch’s Constructor Theory framework, exposing key concepts—from simple Tasks and branching substrates to quantum-gravity and electromagnetism—entirely in code. Includes a “universal constructor” that can bootstrap itself from a list of Tasks, demonstrating self-replication and the power of Constructor Theory. “A demonstration of how constructor theory could be explored in code, not a high-precision physics engine. For the formal definitions, see David Deutsch

C++ pop quiz time: what are the values of a.a and b.b on the last line in main of this program? #include <iostream> struct foo { foo () = default ; int a ; }; struct bar { bar (); int b ; }; bar :: bar () = default ; int main () { foo a {}; bar b {}; std :: cout << a . a << ' ' << b . b ; } The answer is that a.a is 0 and b.b is indeterminate, so reading it is undefined behaviour. Why? Because initialization in C++ is bonkers. Default-, value-, and zero-initialization Before we get into the
