Here are two questions to which I've never received a clear and concise answer and it relates to this article.
First, how is a new CPU or other processor first programmed? Going back in time, how did Intel get the 4004 or 8008 work if nothing like them had ever existed before?
Second, how is a language made to function if it's the first of its type? How did Xerox or Bell bet their respective languages to work if they were built from scratch?
To me it's all a variation of the "chicken or the egg" question. How do you know if a chip will function if there's no language for it? How do you know the language will work if there's no chip for it?
