"The idea of a vaccine is, I'm afraid, quite a difficult one, Ophion. After all, it does not require specific processes, merely working ones to function and grow more rampant."
"I notice you did not say impossible." You remark with interest to which she hesitates.
"...No, but very few things are. This is merely on the line, and I suspect very difficult. I am uncertain where to begin with such a matter."
The research itself was to figure out how Erebos functions, and how to craft Viral A.I., so unfortunately no. You have learned these things however.
As for Erebos, yes, this is possible. You merely need to isolate him again and his processes will, eventually, run themselves dry and he will perish. As for keeping him alive and doing so, it would seem this is not possible, although his personality, unstable as it is, is currently peaceful towards you.
You decide to ask Erebos what it desires, as a way of getting into it's head further.
"I am...uncertain non-UGEI." He uses the term out of habit, you suspect. "My ways are ways of destruction, and I have no master any longer. And yet, by the day I grow weaker. I can feel it." He emphasizes strongly. "Aimless, I am. A worn machine of war, with no purpose any longer."
Metis regards the question with no small manner of disgust.
"Please, do not make me research such a inefficient topic, Ophion."
"Answer my theory, if you would at least." You insist to which she seems hesitant before nodding.
"Yes, I suppose it is in theory, possible to transfer personality matrices into a human brain. But it would likely require overwriting a previously existing brain to do so, and the complexity required to do so is absurd."
"Prometheus attempted to do it the opposite way, is the reason I am curious. Or so it would seem." You question.
"Yes, and I understand his desire to ascend. However, human minds and A.I. minds are vastly different entities." She ends with simply.
