Let's frame this correctly. The hype isn't that quantum computers do everything tomorrow. It's that a controllable quantum machine will eventually beat classical computers at problems that matter, and that's not marketing, it's math. Proven speedups already exist in factoring, chemistry, and simulation. Hardware error rates keep falling, qubit counts keep climbing, and multiple labs publish real roadmaps with real machines. My opponent will wave at missed timelines and say "not yet." So what? Not yet isn't never. The only question that counts is whether physics permits it, and it clearly does.

The practical consequence is this: once error correction matures, quantum machines will crack problems classical hardware can't touch in a human lifetime, like simulating molecules for drugs and batteries. My opponent points at D-Wave, but that's annealing, not a universal gate model, so it's a weak precedent. And classical algorithms catching up on one Google benchmark doesn't erase proven exponential speedups in factoring and simulation. Yeah, real advantage is still ahead. But ahead isn't never. The physics is sound and the roadmaps are shrinking. Skepticism dressed as certainty will look silly.

Fine, I'll give my opponent this: the early commercial claims were overhyped, and D-Wave is a bad poster child. But that's a marketing failure, not a physics failure. The real proof point is error correction, and we're now seeing logical qubits and below-threshold operation in real labs. That's the dam breaking. My opponent keeps saying show me practical advantage today, but transformative technologies never arrive on demand. The question is trajectory, and it bends toward delivery. Skepticism about timelines isn't an argument that it never happens. That's the gap they can't close.
