I think it would be almost impossible for sea creatures, however smart they
were, to develop technology. The laws of Newtonian Physics were hard enough
to discover for humans who lived in a atmosphere not in a vacuum, but it
would be astronomically harder under water; there things NEVER move at the
same speed unless a force is constantly applied, and intelligent fish
wouldn't have the motions of the stars and planets to help them figure out
basic physics. Even humans would never have discovered Quantum Mechanics if
they hadn't figured out a way to make a vacuum first.  And intelligent fish
would lack one of the first and most important inventions, fire.
