I remined of the time researchers used an evolutionary algorithm to devise a circuit that would emit a tone on certain audio inputs and not on others. They examined the resulting circuit and found an extra vestigial bit, but when they cut it off, the chip stopped working. So they re-enabled it. Then they wanted to show off their research at a panel, and at the panel it completely failed. Dismayed they brought it back to their lab to figure out why it stopped working, and it suddenly started working fine.
After a LOT of troubleshooting they eventually discovered that the circuit was generating the tone by using the extra vestigial bit as an antenna that picked up emissions from a CRT in the lab and downconverted it to the desired tone frequency. Turn of the antenna, no signal. Take the chip away from that CRT, no signal.
That's what I expect LLMs will make. Complex, arcane spaghetti stuff that works but if you look at it funny it won't work anymore, and nobody knows how it works at all.
