> It's stuff like this that always reminds me of Wallace Stevens' > Connoisseurs of Chaos with its wonderful line "the squirming facts > exceed the squamous mind."

Like writing before, machine is the new incorruptible instructor of the chemical brains, teaching the precision of a never forgetting memory.
