Quantum in the Loop
Do Quantum Neural Networks Help Us Get to AGI, or Do We Just Want Them To? A Technocrat's Discernment. July 8, 2026. Companion to "The Jacobian in the Mirror." A reader wrote in after the J-space piece with the good, dumb question. The best questions are almost always dumb ones. Hers was this: if we are getting close to something we might call machine cognition, do quantum neural networks matter for the road ahead? Do they help us get to AGI? Do they help us build the kind of AGI that would count as an entity in some deeper sense than the functional one? I have been sitting with variational circuits on a CUDA-Q setup at home and a DGX Spark next to it, running benchmarks the two of us can compare on the same problems, and I think I owe an honest answer. So here it is, in one line: quantum neural networks will probably make a modest positive contribution to the road to AGI. Almost none of that contribution will be on the critical path. And the more interesting question i...
