Are they serious about pursuing the goal of ending the world? Or is this a joke?

The response to 'How can I help?', namely 'You are surely helping already' seems like the biggest clue to me that this is a joke.

I liked this one:

Q: Why do you want to end the world?

A: CAE is devoted to practical, pragmatic solutions. We’re interested in the how, not the why.

It is a joke. Some people may find it difficult to joke about (the desensitization problem), but not everyone evidently. As a joke, it has some sinister merit IMO.
