A tree or a duck image might be "what used to be" and valued, indeed, in the museum of natural history. That part of technology frightens me. As for advances, my cliche is just look back 20 years then look at the very pc you use today. There is even research going on to use diamonds in "chips" or processors, with lightening speed and no problems with heat! I now have 5 fans in this computer and the largest fan is me.
