I had in mind the situation where the spoken version was too ambiguous to transcribe, not the typical proofreading situation. So having him do it immediately isn't too unreasonable. Dynabook, a portable information manipulation device about the size of a notebook. It would include every spiffy accouterment known to computer science. Here we have a machine that can hold encyclopedia, technical manuals, histories, images, sounds, and communicate them to anyone else with a similar machine, etc.
Redundancy is a healthy thing in research.
By asking the same question again new viewpoints may be discovered. By challenging existing ideas, directly or indirectly, we come upon new truths. Please consider carefully. I worry that easy access to incomplete systems of information may cause a television-like stupor to descend upon us, ultimately decreasing our involvment and interaction with knowledge.
