The use of the word "emergent" is concerning to me. I believe this to be an... exaggeration of the observed effect. Depending on the perspective and the knowledge of the domain, this might seem to some ad emergent, however we saw equally interesting developments with more complex Markov chaining given the sheer lack of computational resources and time. What we are observing is just another step up that ladder, another angle to enumerate and pick the best token next in the sequence given the information revealed by the proceeding words. Linguistics is all about efficient, lossless data-transfer. While it's "cool" and very surprising.. I don't believe we should be treating it as somewhere between a spell-checker and a sentient being. People aren't simple heuristic models, and to imply these machines are remotely close is woefully inaccurate and will lead to further confusion and disappointment in the future.
