Two comments:<p>IMHO, Python would have been in a far better place if Guido and his team would have been getting paid to maintain and evolve Python, the language, rather than apps and platforms based on Python. I think in the early days at Google he was able to do so, later, appengine took most of his time.<p>Dropbox is still a startup - despite the substantial investments rounds - since it is still relying on external money (investments) to grow.
