In computing, the suit of wands represents encoding - the way we pull information out of wires and make information out of alphabets and the ways we get information from one place to another. The fifth card in a tarot suit is an overreaction to the trauma of the nature of the suit when it encounters the world. The fifth card of the suit of encoding is noise. Noise is the difference between what the encoder intended and what the decoder receives.
Noise is something to be worked around. Noise is unpredictable in the particular but is predictable in aggregate, so we can communicate in the presence of noise with redundancy - we repeat the same thing three times, and choose the two that look the most alike. We measure again and again and take the average.
Consider the well understood frictions and obstacles in your path - the little work-arounds and blockages in the flow of your effort. Consider how surprises even out at scale, and whether or not the sum of your mistakes goes to zero in the long run.
