Peter wrote this about the same time I first met him at the Lisp Users Venders conference in San Diego. I had just had my Common Lisp book published by Springer Verlag. Fast forward a few years and he helped me a lot my reading through my Java AI book manuscript, offering a lot of good advice. A year or two after that when I had lunch with him at Google I was really surprised that he had moved on to Python. It is ironic to me, that I followed him to mostly using Python, but 20 years later! In the end, it is all about getting valuable code written and deployed, not using a particular language. That said, I still enjoy using a variety of languages, even though Python is the most practical and productive language for what I work on now.
