Which binary data representation? If I'm sending a Java object, do you think a C program will be able to just use it? Or for that matter, do you think two different C++ implementations, maybe on different platforms, will use the same binary representation of a class object?

just need an standard for that

Java has a standard, each C implementation has a standard, Python has a standard, etc.

The problem is that each of these standards is different, and impossible to modify.

So, we need something that can serialize one standard to a wire format, and then deserialize from that wire format to another standard.

Oh wait...

so we cant create a standard that can eliminate serde part????

I'm assuming you may be trolling me, but no, that can't realistically be done.

seems like skill issue to me
