They're cool but they're never taking over the planet. Suckers.

On a more serious note, it's very interesting to see the different mechanisms that nature develops for adaptability.

It seems like there's a trade off here between heredability and adaptability, with cephalopods favouring the second one. Meaning on a long scale their evolution might be slower but it allows them to overcome challenges on the short term more effectively. If I understood correctly, as I haven't read the whole thing yet.
