## Resource

Sabine Hossenfelder says quantum computers are only useful for breaking codes. She's wrong — and my undergraduates are building the proof. What's happening in my lab right now has nothing to do with cryptography, and everything to do with the future of AI. I'm a cosmologist at UC San Diego teaching undergraduates to build, program, and eventually launch quantum computers — possibly to the Moon via Artemis! We cover: why Sabine's code-breaking verdict misses the real story, how free tools like Quantum Rings are closing the education gap Sabine thinks is a hardware problem, why Q-Day just got moved up to 2029, what my students are actually doing with quantum computers in my lab, and why the next generation of quantum physicists won't need a billion-dollar facility to train. The bottleneck isn't the hardware. It's what we're teaching — and who we're teaching it to.
