I completely agree with this myself (and have for a long time before I even read any of Levin's frankly amazing work) and I think of the answer to this as more like a float/real-numbered thing - the amount of consciousness/intelligence/agency as a fraction of overall energy usage or something maybe? And that probably will lead to one constantly having to try to work out where the heck zero and one are all the time eh? heheh : )
I think it's fun and fascinating as well though for sure, and I think that even stuff as simple as a reaction-diffusion simulation, can actually contain some tiny elements of agency (just like this paper does with it's self-sorting cells!) Who cares what the scale is, right?, it's the same phenomena at the tiniest scales in my opinion, that led to life, that led to humans.
