Just thought of another one.
Trains, they only deal in one dimension forward and reverse. Do they still have drivers??
cars, forward reverse, left and right, driverless yet?
aeroplanes, runway to runway, programmed routes in the sky, surely they can that without pilots,
and you you think that the first thing to go driverless will be helicopters, which take off and land at in planned, unsurveyed places, doing often unplanned operations onto moving targets is what we should worry about.
i will start thinking about it when my car can drive me to the pub, wait for me while I have a few, then safely deliver me home again.
