We already see the "intense, relatively widespread, sudden, superficial interest in bitcoin", so what remains to be seen is if it "will eventually be followed by a sudden loss of interest in bitcoin." Since we already have the first half of the bubble phenomenon, it is not unreasonable (or BS) to suspect the second half will follow. Especially since we are seeing lots of bubbles these days. Remember, a bubble doesn't mean something is worthless, but only overvalued, e.g. the housing bubble didn't mean that housing was worthless, but it was overvalued.
