Some confusion could be down to the use of long and short scale systems of numbering. Also, if you google 'billion' one of the replies is "a 1 followed by 12 zeroes". So JQ's calculation is in fact called 40 billion, not the 40 trillion he states.
But I agree, it is all a bit confusing, and now that we we can see how confusing just agreeing on the names of the numbers is. we shouldn't be too surprised that it's all fallen in a heap
