Criticism
Exploratory engineering has its critics, who dismiss the activity as mere armchair speculation, albeit with computer assist. A boundary which would take exploratory engineering out of the realm of mere speculation and define it as a realistic design activity is often indiscernible to such critics, and at the same time is often inexpressible by the proponents of exploratory engineering. While both critics and proponents often agree that much of the highly detailed simulation effort in the field may never result in a physical device, the dichotomy between the two groups is exemplified by the situation in which proponents of molecular nanotechnology contend that many complicated molecular machinery designs will be realizable after an unspecified "assembler breakthrough" envisioned by K. Eric Drexler, while critics contend that this attitude embodies wishful thinking equivalent to that in the famous Sidney Harris cartoon (ISBN 0-913232-39-4) "And then a miracle occurs" published in the American Scientist magazine. In summary the critics contend that a hypothetical model which is both self-consistent and consistent with the laws of science concerning its operation, in the absence of a path to build the device modeled, provides no evidence that the desired device can be built. Proponents contend that there are so many potential ways to build the desired device that surely at least one of those ways will not display a critical flaw preventing the device from being built.

Famous quotes containing the word criticism:
“The critic lives at second hand. He writes about. The poem, the novel, or the play must be given to him; criticism exists by the grace of other men’s genius. By virtue of style, criticism can itself become literature. But usually this occurs only when the writer is acting as critic of his own work or as outrider to his own poetics, when the criticism of Coleridge is work in progress or that of T.S. Eliot propaganda.”
—George Steiner (b. 1929)
“Nothing would improve newspaper criticism so much as the knowledge that it was to be read by men too hardy to acquiesce in the authoritative statement of the reviewer.”
—Richard Holt Hutton (1826–1897)
“Like speaks to like only; labor to labor, philosophy to philosophy, criticism to criticism, poetry to poetry. Literature speaks how much still to the past, how little to the future, how much to the East, how little to the West.”
—Henry David Thoreau (1817–1862)
