On the LTCM disaster:

I don’t yet know the balance between whether this was a random event or whether this was negligence on theirs and their creditors’ parts. If a random bolt of lightning hits you when you’re standing in the middle of the field, that feels like a random event. But if your business is to stand in random fields during lightning storms, then you should anticipate, perhaps a little more robustly, the risks you’re taking on.
