Did Fisher understand the technology he promoted?

Did Fisher understand the new technology, or did he simply assume that new meant better?

He understood the technology well, but was also very sure that newer meant better.

Fisher's long work in gunnery and torpedoes made him a knowledgeable and passionate technophile. His weakness was excessive confidence that a newer system or ship would provide the better answer. That distinction helps explain how a technically informed reformer could still undervalue adaptable older hulls.
