Which part of the statement? The idea that if GR cannot be quantized because past knowledge lets you know future knowledge then this implies Newton cannot be quantized, or the fact that you CAN quantize Newton?

No, they certainly do not! Newtonian physics does not consider time to be a coordinate of the geometry. One would think that someone as versed in modern physics as yourself would be well aware of that fact.
You'll forgive a vagueness of language. Your claim was that the deterministic nature of the theory (i.e. if we know the past, we can know the future) is the reason that GR cannot be quantized. I was speaking of this particular feature of time (knowing the past lets you know the future) that the two theories share. I did not mean to imply that time was exactly the same in each.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.
