Quantum computing is hailed as a transformative force in technology, promising breakthroughs in drug design and battery technology, but major hurdles remain. The physics needed for quantum computers is challenging; although companies like Microsoft and Amazon claim progress, no definitive leader has emerged in this competitive space. Experts estimate practical quantum computing capabilities at least five to twenty years away, casting doubt on its immediate impact on encryption and data security. Critics suggest that ultimate viability may never be reached, despite ongoing investment and research.
Today's quantum computing investors are essentially backing competing physics experiments in a derby to create Feynman's machine. While they've made progress, no clear winner has emerged.
The physics needed for his machine of a different kind that takes advantage of quantum physics' tantalizing weirdness requires really hard physics.
