> The abstractions ... [are] very surprising

From this[1] insightful video essay by Kyle Kallgren:

>> Metaphor Shear -- That feeling all users experience when you realize the metaphor you are working in is bogus. When the computer fails you and you remember that there are a hundred translations between input and output. Codes and translations we don't have the time or patience to do ourselves. Intellectual labor that we've surrendered to a device.

>> The joke at the center of Douglas Adams Hitchhiker's Guide To The Galaxy is about metaphor shear. The answer to an important question lost on its long journey from input to output. A computer glitch so huge, so strange and so embarrassing that its programmers have to make a computer the size of a planet to file a bug report.
