With a musical instrument, it’s awkward at first.  All thumbs.  Uncomfortable.   Noise.  With practice, the musician becomes self-contained vs. consumed by the instrument; co-creating music.  So it will be with personal technology.  Now, a prosthetic of mind, it will become a prosthetic of being.  A violinist with a violin.  Us with our gadgets, embodied, attending as we choose.
