What this means is we've been grossly underestimating the number of potential users of Bitcoin. We've restricted it so far only to humans, based on old models of non-digital currency. That is a huge miscalculation. Now "things" will own Bitcoins as well, and use them to interact with each other. The number of "things" in the world is massively larger than the number of people. In terms of Bitcoin price, this is huge.

Someone answered it already but to expand this to the sci-fi edge of possibility, there has been talk of non-human intelligence programs being able to remain alive by performing a task to exchange for bitcoin. Like an autonomous taxi that performs a service for bitcoins then buys gas and maintenance in order to continue it's hard-coded "purpose".
