Why claims of unprecedented technology can obscure historical lessons

Would a briefing pack on lessons from history help people developing new military systems?

It is worth doing, but advocates of new technology often dismiss historical comparisons as irrelevant.

A briefing pack on lessons from history receives a positive response, followed by a practical objection. Advocates of a new military system can dismiss past experience by claiming that the technology has changed warfare so completely that earlier examples no longer apply. The criticism is that this recurring enthusiasm for technology can lose contact with operational reality.
