So often in my new experiences complexity is the selling point, the starting point, and/or the proof of your value. People (customers) don’t share this vision. People are intelligent but must be set free to construct the level of complexity they are comfortable with, or need.

Complexity isn’t designed but rather rises spontaneously through self-organisation. Start with basic or simple interactions and allow more complex behaviours or patterns to emerge.
From an old project proposal, source is likely from theory of emergence.
