: For all of my teenage years, I listened to the same sort of music. I'd have
: the same dozen albums playing in my car and in my portable CD player and
: in my stereo at home. Take those away, and I wouldn't remember how the
: tunes went. A week after listening, I might be able to remember snippets,
: but now how the whole thing went together.

: Last summer, I went off a certain brand of antidepressants, and it was
: suddenly like I had a jukebox in my head. I never would have thought to
: connect the two.

I wonder if you could give agents medication that stops them laying down long term memories and have them totally forget what they had been up to?

: I don't know. My understanding of biology is that it's not a finely tuned
: machine. Shake it and it rattles. It's not a Von Neuman machine, it's a
: yardsale toaster.

: The Geas used to steer Bornstellar Makes Eternal Lasting makes sense, because
: Forerunner biology is engineered to make it possible, same as the
: mutations. The idea of the Geas surviving a hundred thousand years of
: genetic drift when every other bit of Forerunner technology that doesn't
: have dedicated repair systems to keep it going is harder to swallow.

Yeh, you would have to engineer in active mechanisms to preserve the geas and those would have been found long ago by UNSC (or pre-UNSC) scientists.
