    This isn’t exactly new. I heard a few years ago about a situation where the ai had these wires on the chip that should not do anything as they didn’t go anywhere , but if they removed it the chip stopped working correctly.

      That was a different technique, using simulated evolution in an FPGA.

      An algorithm would create a series of random circuit designs, program the FPGA with them, then evaluate how well each one accomplished a task. It would then take the best design, create a series of random variations on it, and select the best one. Rinse and repeat until the circuit is really good at performing the task.

        I think this is what I am thinking of. Kind of a predecessor of modern machine learning.

        I thought of this as well. In fact, as a bit of fun I added a switch to a rack at our lab in a similar way with the same labels. This one though does nothing, but people did push the “turbo” button on old pc boxes despite how often those buttons weren’t connected.

            After the 486, there were pentiums built at shops that still used 486 cases. In my experience the button wasn’t plugged in.

          My turbo button was connected to an LED but that was it

        I remember that as well.

        Edit; moved comment to correct reply.

      Yeah, I’ve stumbled upon that one a while back too, probably. Was it also the one where the initial designs would refuse to work outside the room temperature 'til the ai was asked to take temps into account?

      Sounds like RF reflection used like a data capacitor or something.

        The particular example was getting clock-like behavior without a clock. It had an incomplete circuit that used RF reflection or something very similar to simulate a clock. Of course, removing this dead-end circuit broke the design.

      I remember this too, it was years and years ago (I almost want to say 2010-2015). Can’t find anything searching for it
