       | signals in response to light, and the robot triggers a walk cycle
       | when it sees that signal.

             | If you take a small plot of wild land, say 50'x50' and
             | visit it everyday watching all the various mushrooms which
             | will grow there (there will be far more then most people
             | realize or expect) and try and find the sense in where and
             | when they fruit it becomes difficult to write it all off as
             | simple biological responses to environment/following the
             | food/etc, and even if you do look at it that way and start
             | adding up the possible causes and effects you can end up
             | with such a long list that it becomes difficult to not see
             | it as some sort of at least instinctual level intelligence
             | and that the growth of mycelium often has more in common
             | with crawling than mindless growth.
             | 
             | For example, many mushrooms are very good at fruiting just
             | out of sight from trails, walk 20' off the trail, turn
             | around and suddenly you start seeing mushrooms. Instinct is
             | to say that all the mushrooms which grow within sight of
             | the trail get picked by curious people or kicked by
             | children but if you start looking for remains and stumps
             | and mushrumps and those hard to spot just starting to fruit
             | immature buttons, you find surprisingly few. So you think
             | environmental, the trail alters windflow and runoff, animal
             | movement, etc, but than you notice that this is true of
             | even those small trails created by a fox or children which
             | only affect a bit of low growing undergrowth so only has a
             | tiny effect on a very localized area. On and on it goes
             | until you run out of explanations.
             | 
             | I am mostly convinced there is some level of intelligence
             | here and we just can not see it because it is so very
             | different from what we understand as intelligence. But, I
             | may just spend too much time with mushrooms, during the
             | season I always seem to have at least a dozen various
             | mushrooms which I will visit everyday to watch them grow
             | and rot away.

       | Recently I saw a video of a turtle which was given a skateboard.
       | It quickly learned how to zip around the house, chasing the cat,
       | etc. It was a simple demostration of how technology, even as
       | primitive as the wheel, can augment the abilities of an organism
       | - especially a living being with sensors (eyes) and neural
       | network (brain).
       | 
       | It also reminds me of the goldfish in a bowl, attached to a small
       | motorized vehicle, which was given the ability to navigate it by
       | swimming in different directions. It soon learned to use this
       | system as an extension of its body, exploring the house, bumping
       | into things like a Roomba with a live brain.
       | 
       | Suppose it's in the same field of exploration as those super-
       | soldiers with Gundam-style body suits and computerized helmets
       | projecting a live data feed to their retinas, maybe eventually
       | embedding neural connectors directly in the head.
