A computer program designed by humans to assist with human constructs can infer meaning from what appears to be mostly noise to humans. It hits us hard because communication through complex language is the defining trait of our species. It manages to do what we do, and many people are intrigued by the results.
Are we just observing the results of our actions or did we just take one more small step towards the singularity?
