Challenging enough question. But, now along comes Martin Monti and his colleagues in Belgium. They add a new test for consciousness, applied to fifty-plus folks in a proclaimed vegetative state. Monti et al., using an MRI machine (which monitors for active neurons in the brain), watch these folks' brains when they are asked a question. And, amazingly a handful of the patients' brains light up 'Yes' or 'No' just like your brain or mine would if we were asked a question. These folks are thinking—they are responding to a specific question. They are not vegetables after all! Or at least I don't think so.

Think of the implications for: my life (now I can communicate with my family, my health care providers); my care (now I can respond to questions about my health care and comfort); health care in general (do we now spend the time and money to do an MRI on every person thought to be in a vegetative state?); understanding of the conscious and the unconscious (in what kind of thinking-space am I living?). As is often the case, in the scientific paper explaining this new MRI-thinking, most of these issues are either ignored or barely brushed up against (although, to the journal’s credit, the article is accompanied by an editorial that begins to explore some of these issues).

If ever I'm in that condition, pull the plug! Lying there with my consciousness trapped in a non responsive body is about as abhorrent as I can imagine.

Both ends of life are blurred nowadays. And it will get worse.
When is an Artificial Intelligence alive? That isn't a valid question... ... yet...
