becoming less human through GPS

so in a taxi in madrid yesterday, i felt concerned that the satnav
system the driver used took all the skill (the "knowledge, as
london Hackney CarriageCab Drivers will tell you) out of the job
thru dumbing down.

then I thought "ah, but at least the driver cannot cheat me, as I can tell
that he's asked the satnav box for the right destination"

then I thought " ah, but if he's really smart, then he could hack the map
or algorithm to lie to me..."

then i thought "nah, if he was that smart, he'd either not have a satnav,
or he'd work for Nasa or Galileo or Garmin"...

either way, its demeaning...
