We don’t expect 100% reliability from humans-humans will slack off, steal, defraud, harass each other, sell your source code to a foreign intelligence service, turn your business behind your back into a front for international drug cartels-some of that is very low probability, but never zero probability-so is it really a problem if we can’t reduce the probability to literally zero for AIs either?
You want the ai aligned with writing accurate documentation, not aligned with a goal thats near but wrong, e.g. writing accurate sounding documentation.
