All of which raises the question – your task, burden, privilege, call it what you like – a question which men and women, great and not-so of every color, creed and sexual persuasion have asked since they first had the language to do so, and probably before: Does Anything I Do Matter?

And knowing that the only alternative to your grief is the nothingness that’s fast approaching, you try to embrace your own sorrow, to be open and empty and let it all pass through you.

Don't repackage your fear and try to sell it to me as indifference.

I think that anyone who grew up reading and being taught the Bible, as I did, can't help but have their prose shaped by it later in life. I still have deep, almost primal responses to the language of scripture, and I think that comes through in all my writing.

It's all an approach; it's all a glide path to the moment of genuine singularity; genuine artificial intelligence.
