Quantum Computing Is a Lie (Here’s What I Discovered)

A former big tech software engineer shares a personal account of exploring quantum computing after attending an internal R&D conference. The post covers basic quantum computing concepts like superposition, entanglement, and qubits, then argues that despite theoretical promise, quantum computers remain practically limited due to a severe algorithmic deficit — only a handful of algorithms (like Shor's and Grover's) can extract useful results from quantum outputs. The author also reflects on the philosophical implications of quantum mechanics, including entanglement, time manipulation experiments, and simulation theory, before concluding that quantum computing is far from the trillion-dollar industry it's hyped to be.
