I'm not entirely convinced of this argument myself, that it's impossible for us to "truly" understand how brains work . However, I entirely agree with the sentiment: We don't necessarily understand brains now, but we don't dismiss their capabilities just because we can't explain precisely how they do what they do. By the same token, complex tools like deep learning shouldn't be dismissed just because we can't satisfactorily interpret them.
