So I do think it's important to keep them separated, but also acknowledge that they do not quarantine from one another, absolutely.

Can I tell two quick stories, one on this scientific image versus manifest image, and one on the asymmetry of time? So on the former, Kurt Vonnegut, near the end of his life, read Stephen Hawking's famous book, A Brief History of Time.

And Stephen Hawking says at one point during the book, why is it that we remember the past but don't remember the future? And Kurt Vonnegut, again, at the end of his life says, I got to tell Dr.

Hawking, when you get to my age, you remember the future quite well.

He was really good at remembering the future.

He was very good.

The second thing is the asymmetry of the past and the future.

not careful there.
