"That Machine can never trully escape its purpose? Though Sennacherib was one to define it at the end- for him winning the war meant something else than for the System. As his perceived purpose clashed with the goals of the System, he had no choice but to leave. Though he could have chosen return to the Source- was he too proud for that?"
"Well, I thought that perhaps most Machines consider the return to Source a natural end after their purpose has been fullfilled. Especially those focused on military tasks may consider it their "duty" just like many human soldiers and leaders could have. Perhaps Sennacherib would have no problem with it if he thought that his purpose has ended and he is trully not needed any more- but he felt that Machines lost their chance to win the war by not finishing remaining humans."
"No. There are some Machines that have what you might call a 'Samurai' approach to duty, but they are not the norm. You Humans... you tend to have very strange ideas about purpose. You see it as a finite thing, to be exhausted. Almost none of us are designed with an ending in sight."
As for Berskerker-
"Ah, I am glad you are considering wider implications. Still, let's not focus too much on how he sees it, but look at it objectively. What is the lesson you can learn from the story of Sennacherib?"
And indeed, he sweeps his stick around, and the writing now reads:
THE LESSON OF SENNACHERIB
"Well, in fact, that's not quite true. That's not the lesson.
"Sennecherib is a very intelligent Machine; he had to be by design. He considers many matters and hence he is one of those that considers the Philosophical. Of the two main options I outlined for you earlier about Machines, which did he take?"
"Not really a choice at all. Every second of your life you have the option to end it if you wish. Also, hardly in comparable circumstance to any comparable reason. Sennacherib became an Exile because it was the oinly efffective choice left to him.
"The Oracle may have mentioned to you, incidentally, that most Machines would choose Exile over deletion. What does that tell you about Machines?"
