Line of reasoning? That evolution is an optimization process, and that human intelligence is an optimization process - hence both are likely to reach good solutions for intelligence eventually, and if there's a strong optimum in the design space of those, then both are likely to converge at least in some areas.
What's "we"? Human technological civilization.
What's "nature"? Evolutionary process that already produced working brains.
Why? Ditto.
