Historian: The main section of space telescope Webb is complete and ready for testing [link]. This main section comprises the frame, mirrors, and instruments package. To say that these parts are state of the art is silly because these parts greatly moved the state of the art forward.
Physicist: Webb will see more infrared than Hubble [link] does. Webb will see further than Hubble. Webb will see with higher resolution than Hubble. Hubble continues to amaze us well beyond the time it was expected to operate. Webb will take our amazement to a new level.
