But Duke Nukem was developed with visible progress.

We are still not factoring 21, let alone 35, let alone numbers with thousands of digits.

Quantum correction algorithms (that would allow factoring of thousands of digits) begin to work when the gate fidelity and other parameters are above certain threshold.

  • > gate fidelity and other parameters are above certain threshold

    A threshold that might be beyond what the physical properties of our universe allow. It is still unclear.

    • This is what bugs me about both quantum computers and commercial fusion power. There's so much talk about how it's just inevitable and will happen soonish, but a lot of the evidence suggests, in some cases strongly, that it might not ever be possible.

      I find it weird how bleeding edge research, at the very edges of both physics and engineering, is treated as though it's a market development about to drop. Possibly a consequence of pure R&D having all but died? Getting funded requires pretending there's a business plan for what you're working on?
