A lot of the books I have read in the recent past have to do with trying to get a working definition of life and/or consciousness. I picked up ‘Life as No One Knows It’ to get more perspectives in that direction, but it gave me something else by shifting the frame. At exactly halfway through the book, there is a line that goes “what will really be alien are examples of life (biological or technological) that have traversed a completely different evolutionary trajectory than we have.” And that’s important because if we keep looking for markers based on life on earth, we may not find it anywhere else in the universe. It’s thus important to find a framework that is agnostic of life as we know it, so that we have a measurable way of recognising and classifying signs of life/intelligence when we come across it.
