Python is really good at gluing code together. I predict that Python will continue to see tremendous success if it can be fast enough that using it as glue is a no-brainer. As an example, I maintain a SaaS with a backend written in Python. Only one third of the time in the backend is spent executing Python code, the rest is spent talking with remote services (database, third-parties...). Switching to a language an order of magnitude faster would barely change the perceived responsiveness of the backend. On the other hand, I welcome any speed improvements in the interpreter because from my perspective it really is free performance.
