*already* computers generate bytecode that's improbable/impossible for humans to decode. Computers have been that way from the day of the very first compiler in the early 1950s. [thanks Grace Hopper! awesome lady she was] So for a computer to be incomprehensible to a human is already here. Now, can we design a computer more intelligent than us? That's where it's tricky. _what's the measuring stick_? _How_ can we measure the difference between "incomprehensible" and "super-intelligent" - if we're incapable of being _more intelligent_? We have to be at a higher level to measure at a lower level. Even when we measure bigger things, it's thanks to the power of Optiks that things are measurable: How else does the Universe fit in a 2mm circle in front of our heads? Even if we designed a chain of less and less comprehendable computers going *upwards* to reach the "super-intelligent" and have them back-translate DOWN to our level... we have no way of verifying their correctness. No way to measure. No way to know.
