Thinking machines are consistently in the news these days, and often a topic of discussion here at 13.7. Last week, Alva Noë came out as a singularity skeptic , and three of us contributed to Edge.org's annual question  for 2015: What do you think about machines that think?
In response to the Edge.org question, I argued that we shouldn't be chauvinists when it comes to defining thinking  — that is, we should resist the temptation to restrict what counts as thinking to "thinking like adult humans" or "thinking like contemporary computers." Marcelo Gleiser suggested that we're already living as transhumans , enhanced by our technogadgets and medical improvements. And Stuart Kauffman considered Turing machines, the quantum and human choice .
In addressing the relationship between humans and thinking machines, all three of our responses — and those by many others — raised questions about what (if anything) makes us uniquely human. Part of what's fascinating about the idea of thinking machines, after all, is that they seem to approach and encroach on a uniquely human niche, homo sapiens — the wise.
