TECHNOLOGY

At present, there are multiple tracking devices, and still we have the visual prerogative, most of the time. It only requires a subtle shift in emphasis to use the tracking information to crosscheck internal estimates. In the 1970’s when ARPA was new, Future Shock (Alvin Tof? er 1928-2016) considered a technological world we humans would be compelled to want to operate, or else suffer a deep collective anxiety. Now in that future, we are in the midst of discovering a deeper impulse: To be glad to go off watch, not unlike the all-too-common event of a ship’s bridge team relieved to hand over full navigational control to the just-embarked pilot. Controlling the ship is not overly complex, until the contexts of con? ned and dynamic waters no matter how familiar raises the risks to levels nearly unmanageable by humans.

Letting go is a reasonable response to anxiety, just as narrow- er safety margins are the inevitable outcome of control by high- timent may be, we must also guard against losing interest in ly technical and complex systems of sensors, logic, parameters, what makes things work, or in the responsibility for necessary and redundant power sources. But letting go operationally also skills and understanding. What is routine in maritime work seems to include the rapid decay of asking the Navigational inevitably gives way to the unimaginable.

Question. Maintaining responsibility requires participation. A noteworthy trend is the diminishing value of navigation’s very foundation; namely, the timely exercise of good judgment.
