What you're describing is endemic across HN (and tech, tbh). Lots of people on here "know" computers/programming/CS very well. They, naturally, tend to use analogies to computers/programming/CS when trying to explain or "think out loud" in their comments. That's fine. It's what they know. The common problem arises when people forget they're analogizing and begin to see their analogy as ontologically and conceptually identical to the thing they were making an analogy for. This requires a certain amount of ego, echo chambers, and self-valorization, so that they never have to face the actual issues with these analogies.

But as many comments here have pointed out, studying neuroscience, for example, usually makes those analogies seem painfully inadequate. The same is true in philosophy of mind, for example.
