What do these two things have in common?

The stor(ies) on Titanic II (e.g., here) and this story on how the banks are back to bundling up risky loans again. 

My favorite quote from the NYT story:

Banks have won over investors by taking steps to make this generation of structured products safer than the last one. But with demand for these products on the rise, credit ratings agencies and regulators are warning that the additional protections are already dwindling, allowing some of the old excesses to creep back into the market. 

And my favorite quote from the Daily Mail story:

Mr Kanerva, of Finnish boat designers Deltamarin, added: 'I can assure you that from a safety point of view it will be absolutely the most safe cruise ship in the world.'
'We are taking into account all of the possible incidents and accidents and we try to simulate all of those occasions.'

And people wonder why we keep making the same mistakes over and over....
