That's a pretty good way to describe how I think about it. Like many innovations, usage probably looks like an S-curve -- slow in the beginning, then a period of rapid growth, followed by a plateau. It's unclear where we are in the cycle, and it's definitely possible that valuations have over-shot. But it seems to me that there's something real going on in addition to the hype, and that potential could be worth a hell of a lot more than $100b globally.
