Having access to the source code actually makes reading machine code easier, so you’re also wrong on this entirely different thing you’re going on about.
You’ve clearly never used a disassembler such as HIEW have you? You get the entire breakdown of the assembly code.
I disassemble binaries daily for work. It’s still not the same as source code.
I never said disassembly or decompiling was easier in any way. I’ll agree with you on that, it’s way more difficult.
Back to the point of the meme though, if you can read assembly, you can read it all.
You’ve never actually compared source code to its compiled output, have you.
