With brains that process information almost like a computer, the sea creatures already use tools and can be social. But they need to make a few changes before they can take over the world.
I think the raven's bigger problem is that they are just too weak. Humans aren't very strong by animal standards but we are strong enough to break wood and rocks. How would a raven ever get past the stone age. You'd need an entire flock of ravens with stone axes to fell a tree.

To be fair, I feel like ravens would probably need a lot less wood than humans do, so branches & young trees would likely suffice.
