> Is it surprising that silicon does too?

Given that human brains and silicon has nothing in common, then yes, it is surprising. What makes you think otherwise?

If evolution has worked out that having specifically optimized pathways for specific actions it doesn't seem terrible that human designed machines are similar.

I feel that's assuming a whole lot of unrelated things, such as machines and humans having anything at all in common.

I get that your take qualifies as stoner philosophy, so I won't push too far, but really. Do give some concrete examples to support your ideas rather than GPT fluff.
