If you ask the fish whether they'd rather have an oil spill or a season of fishing, I wouldn't be surprised if they'd vote for another blowout.

Now, what that means is that there is fundamental indeterminacy from quantum mechanics, but besides that there are other sources of effective indeterminacy.

Technology is characterized by constant change, rapid innovation, creative destruction, and revolutionary products.

You don't work on something for six years and be blind to the myriad of other approaches.
