Computer programmers do it byte by byte. Computer programmers don't byte, they nibble a bit. Computers are a more fun way to do the same work you'd have to do without them. Computers are not intelligent. They only think they are.
Computers are unreliable, but humans are even more unreliable.
Computers can never replace human stupidity. Computers follow your orders, not your intentions. Computers make very fast, very accurate mistakes. Crashing is the only thing windows does quickly. Any errors in spelling, tact, or fact are transmission errors.
