Quantum computing's two real uses: crypto and chemistry, likely replaceable by AI

Perry Metzger argues that quantum computing has only two truly useful applications: breaking cryptosystems and simulating chemistry. The former loses commercial value once achieved, while the latter can likely be handled well by machine learning techniques. Progress on building quantum computers capable of breaking cryptosystems remains slow, making it unlikely to become a billion-dollar industry in the next decade.
