Just as an example of something a human couldn’t understand that a sufficiently smart computer might—writing code directly to binary, without the intermediate step of a programming language.
That would be read as decompiled assembler which humans can understand, though not in large quantities.
Interesting. Consider me corrected.
For anything nontrivial, we need software support to do that—and it still won’t work very well. You might not be absolutely correct, but you’re close.
IDA is a wonderful piece of software, though. A heck of a lot better than working manually.
