Your statement is technically correct (and mirrors my initial feelings) but the comment below that notes that we accept many other abstractions seems more “meaningful” in the larger scheme of things.

For instance, a software engineer who also understands how to design microprocessors would indeed in my own evaluation be a “better engineer” than me (someone who does not). Yet, I wonder if they would be meaningfully more productive than a good software engineer who “just” understands how microprocessors work..
