Based on them being involved in one battle in WW1 and being massively vulnerable to air attack in WW2.

It’s an exaggeration saying that they were outdated in WW1, as they basically acted as a deterrent, but it was at enormous expense and they don’t do much. Too big, too slow, too expensive. The argument was playing out even prior to WW1.

Aircraft carriers took over, as you say.

That 1 battleship vs battleship action (Jutland) was hugely influential on the course of the war.

Also there were several battlecruiser/cruiser vs battlecruiser/cruiser actions.

Faster and cheaper battleships was what they all wanted, and heavy cruisers seem to fill that role.

Jutland was influential, but mainly just resulted in big ships doing nothing.

That is sort of the role nuclear weapons have too I guess?

>Faster and cheaper battleships was what they all wanted

That would be a battlecruiser, and they don't seem to have been regarded as a success.
