Specialized microchips that manage signals at the cutting edge of wireless technology are astounding works of miniaturization and engineering. They're also difficult and expensive to design.

    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.

      I don’t know about AI involvement but this story in general is very very old.

        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.

        Yeah, that probably sounds so unintuitive and weird to anyone who has never worked with RF.

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

        You helped me narrow it down. I expect Adrian Thompson’s research from the 90s, referenced in this Wikipedia article is what you’re thinking of.

          Yes! Exactly this thank you

          For example, one group of gates has no logical connection to the rest of the circuit, yet is crucial to its function

          (I should have gone with my gut, I knew it was ages ago. 30ish years by the sound of it!)
