I'm with you on that one. Nope, not for me. But if I had their money and influence, moved in such circles and wanted to do the adventure/exploration thing, it wouldn't have been on board of anything unproven or experimental. There'd be so much testing and safety measures I'd probably get booted off the project and mocked by all my fellow billionaires for being too cautious. Idiots! What good is money when you're in a million pieces at the bottom of the sea or turned to dust and debris in outer space? 

As for the Titanic, she's a graveyard and ought never to be disturbed. Nor should anything that goes anywhere near the water ever bear that (or a similar) name again. Put it on a No Go list like they do with extremely catastrophic hurricanes and such. Out of respect, if nothing else.

And no, I don't give a hang who thinks that's superstitious nonsense. Some things really are better left alone, secrets known only to whatever Powers there may be.
