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

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.

[–] Gormadt@lemmy.blahaj.zone 10 points 7 months ago

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

[–] RedWeasel@lemmy.world 4 points 7 months ago* (last edited 7 months ago)

I remember that as well.

Edit; moved comment to correct reply.

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

[–] GreyEyedGhost@lemmy.ca 11 points 7 months ago

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.

[–] piecat@lemmy.world 3 points 7 months ago

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

It may interest you to know that the switch still exists. https://github.com/PDP-10/its/issues/1232

[–] FourPacketsOfPeanuts@lemmy.world 4 points 7 months ago (2 children)

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

[–] GreyEyedGhost@lemmy.ca 3 points 7 months ago (1 children)

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.

[–] FourPacketsOfPeanuts@lemmy.world 2 points 7 months ago

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!)

[–] ShepherdPie@midwest.social 2 points 7 months ago (1 children)

Perhaps you're an AI who only hallucinated a circuit design.

[–] FourPacketsOfPeanuts@lemmy.world 2 points 7 months ago

:)

It's been found. Adrian Thompson's research from almost 30 years ago..

So the wires did something
