But also whatever language partisanship I had is gone, and won’t come back in the guise of a new favorite language.

This sentence is worth pointing out as a good attitude. I think the healthiest place to be is using tools you like, but able to appreciate the good bits of other systems.

For instance, as long as I'm not actually working with it, I can appreciate the idea that PHP made it very easy for a lot of people to do something with the web, something that otherwise they might not have been able to do, because it is very easy to get started with. That is worth something, and worth thinking about for those who are building tomorrow's languages.
