The passage suggests that the author would most probably agree with which of the following assessments of optical computing in its present form

A． Although the future of optical computing is impressive, its applications are too limited in scope to justify much optimism.

B． The outlook of its development is positive on the surface, but many claims made about it are misleading.

C． Efforts to develop the technology have been sufficiently positive to maintain the interest of electrical engineers and physicists.

D． Because of design flaws, the task of developing optical computing will require greater resources than are presently available.

E． The state of development of optical computing is too contradictory to allow for an easy assessment of its future.
