Parts of Google's search engine was originally in Python, but the company has since moved on to Java on the front end, C++ on the back end, and Python has been relegated to glue code. On the other hand, Dropbox has been using Python for its entire stack. I believe they made a few performance related contributions to CPython as well. Guido is a great engineer (besides being a language designer), and still writes a lot of code. He would get more satisfaction working at a growing company where Python is a first class citizen rather than at Google.
