Personally, I’m a panentropist (my own creation) - I hold that the spectrum of life/consciousness varies depending on the level of entropy. So a flame has a higher level of consciousness than a piece of paper and oxygen molecules. But when you combine them they increase their level. It’s weird but it might be correct - doesn’t address issues of the hard problem of consciousness however
The ultimate organism is then either civilization itself, or the whole universe, depending on how you want to draw the line.
That is one of the postulates of Integrated Information Theory, which aims to give an account of how consciousness can arise from physical substrates. (The idea seems closely related to the concept of entropy.)
If anything, it seems like the reversal of entropy would be a better description of life. To make paper and oxygen from fire would have higher consciousness than a fire itself
