Why the Mersenne Twister Rules Random Number Generation (and Where It Fails)

The Mersenne Twister (specifically MT19937) rules the world of computing because it provides an astronomical sequence period, excellent multi-dimensional uniformity, and high speed, making it the default pseudo-random number generator (PRNG) for Python, C++, MATLAB, and Excel. However, it fails catastrophically in cryptographic security, memory efficiency, and specific modern statistical tests. Why the Mersenne Twister Rules
