Huh. Can we say that accumulation of anything, as a kind of growth, renders that "anything" meaningless only if the growth is an end in itself? That is, if all meaning is invested into growth, into potential states rather than actual states? Churning through discourse as a means of driving/propelling intellectual capital.
Wording it like that, things are clicking for me. We don't accumulate something to enjoy/exhaust the value of that something - we accumulate something to make it easier to accumulate more of it. It makes sense that this shift would drain that something of any value it would have as an end, because now it is reduced unit of measurement, measuring the rate of growth, or the rate of the increase of the rate of growth, and so on.
