We do things. We might not know exactly how we should do them yet, and we might have a few failures and even accidents on the way, but we try things out and that's how we make progress.
We had a failure. In the Grand Scheme Of Things, a bankrupt Westinghouse is no more important than an Enron or a BHS. A few billion on a failed construction project is very small beer compared to the sub-prime mortgage scam. And nobody even knows if it was thirty or fifty trillion in Credit Default Swaps ten years ago fercryinoutloud.
There's no point whining about it, let's just put the toys back in the pram and get on with stuff.
