An abstraction where "positive" and "negative" mean the same just for safety so they can't be confused with each other.

You’ve never worked with C code that had to run on both big endian and little endian systems that had to share a common byte protocol. Where two bytes in the same order can mean something completely different.

There are a lot of things “confusing” about computer science when you don’t take the time to learn it.

On the contrary, I've worked with 8 and {32,64}bit x {LE,BE} chips many times and wrote quite a lot of network code in C. But you're mixing syntax with semantics.

Which byte is the high order byte is just as much semantics defined by the chip vendor that would be confusing to the uninitiated as “Serverless” would be to an old school net ops person who doesn’t know anything about cloud computing.
