What interests me are the post-Newtonian, extrabiologic implications of a human species able to think and act using clusters of electrons: light, in other words. If the opening act of the evolutionary drama involved a descent from light into matter and language, then it only makes sense that in the closing act, so to speak, we reunite with our photonic progenitor. The role that language--the word--will play in our light-driven metamorphosis is the furry little question that cranks my squirrel cage.
