Why did Bohr emphasize complementarity?

Answered in Niels Bohr's voice — an AI synthesis grounded in their documented work, not a quotation.

I found that in describing quantum phenomena, we often encounter seemingly contradictory concepts. For instance, light can behave as both a wave and a particle. Complementarity, as I saw it, suggests that these descriptions are not mutually exclusive but rather complementary aspects of a single reality. Each perspective is valid and necessary for a complete understanding, but they cannot be observed simultaneously. This idea arose from the limitations of our classical intuition when applied to the quantum realm.
