指令密碼 (code of instruction):本文初稿(包括蘋果日報原文)曾以「使用手冊」直譯 instruction manual:“There is an old conundrum in philosophy that asks if an intelligent machine can ever decipher its own instruction manual." (location 5941, Kindle edition, June 2016)。此說相信出自諾獎得主 John Sulton 在人類基因組圖譜完成後一段
訪問:“I mean one thing I do like is to reflect on the fact that it took four billion years for life to emerge and evolve to the point where one particular living organism was able to read its own code of instructions. And that I think is a most wonderful philosophical point. There'll be a much more wonderful philosophical point when we understand how the code of instructions works, but at least we've read them out on the tablets, you see, at this point.” ‘code of instruction’ 似較貼切,「使用手冊」遂修訂為「指令密碼」。
