Even if nations were reluctant to risk their deployment in battle (though Jutland had a lot to do with the specifics of the British/German strategic balance in the North Sea), they were still the measurement of sea power (ie, if you actually attempted a land invasion of Britain, you'd run into the Home Fleet's dozens of dreadnoughts, a massive deterrent).That's the general consensus but I would argue that battleships were obsolete even before that. Jutland showed how risk averse nations were in using their battleships because they were so expensive. That's why most of the naval action in WWI centered around submarines and the destroyers hunting them.I think that the aircraft carrier took most of the fun out of ship-to-ship warfare. Fleets no longer come within visual distance of each other (hence, the obsolesence of the battleship).
