A phrase that's going to bounce merrily around in my head for awhile: "the dangers of setting up an autonomous process in one's own brain" . (What counts as 'autonomous'? The context of the phrase sounds more like what I call a 'background process' by analogy to computing. And even without getting into brain-hacking (which I would say has not hurt me, except that were I to say such a thing, it would open the door for some wise-ass or two or a dozen ...), there are sub-conscious processes going on in our brains all the time: the visual and auditory pattern-matching processes, for example, that figure out whether a sight or sound we'd not been intentionally paying attention to is something that we need to suddenly become conscious of, like hearing our own name jump out of a blur of background noise, or identifying a particular shape+motion in our peripheral vision as a spider. Anyhow, the phrase is sticking in my mind for the moment, in much the same way that a song can get stuck.)
