Titanic nerd here. There are definitely lessons that we've still not learned. Greed and hubris are easily spotted, but the more insidious enemy that doomed Titanic was complacency. In 1912 there was a real sentiment that man was the master of the universe, that war was a thing of the past, that modern science made ships practically unsinkable... none of that was true, of course.

Jack Thayer, a survivor, later wrote about how the Titanic sinking presaged a sea change in the world, and not for the better:

"There was peace and the world had an even tenor to its way. Nothing was revealed in the morning the trend of which was not known the night before.

To my mind the world of today awoke April 15th, 1912"
