It's amazing how fast he can play his pop-up keyboard,
lighting quick across so many keys;
but only, I notice, just one at a time, not a single chord
yet all the time his fingers never freeze.

Although I see now it's his other sort of digit
doing the work without the need to strain
them all and he's so concentrating he doesn't fidget,
just sits - not using body, only brain.

We know that it needed millennia to form 'homo sapiens'
but seeing the way technology numbs,
our species might quickly evolve into 'homo mobilens'
with fatter bums and much bigger thumbs.
