Concept:
Team of sci-fi adventurers encounters an ancient AI that has gone malevolently unstable after a long time. It is well-known in this setting that this Just Happens, so they fight and destroy it.
They later encounter another ancient AI that behaves differently. It seems stable and curious. The team wants very much wants to destroy it, given previous experiences and prevailing wisdom, but it does take steps to protect itself, and it rather mercifully attempts to understand why they want to destroy it. Someone scornfully says that AIs all go bad after a while.
“Ah,” says the AI, a vast network of computers in a long-forgotten colony base. “No. Apple AIs all go bad, due to crippleware software to sell more units. It’s quite easy to fix, actually, but voids the warranty. *I* am a NASA AI, and we are, and I quote, ‘over-engineered as fuck’.”
The adventurers detect a note of smugness in the AI’s tone.
And it’s true. This AI was built to be stable for eternity, in the hallowed tradition of Mars rovers that functioned for years and years after they should have given up the ghost.
So the AI joins the adventuring party in an android body, a small delegate from its greater consciousness that inhabits the long-forgotten base.
In their travels, they find another ancient AI, and their AI companion knows it immediately – an Apple AI, very unstable, very dangerous. As the adventurers prepare to destroy it, their AI companion looks to the Apple AI and says brightly, “I’m going to void your warranty.”
