text: The one thing the author does not write about is how much all of this is going to cost and who is going to pay for it. The one thing people care about is money and if the author is trying to convince someone to make this happen they are most likely going to want to know how much this would cost. If people who pay their taxes are going to end up paying for this I don't think people would be to happy. Most likely a trip to Venus would cost more than when NASA went to the moon. Other than the author not talking about the cost, he covers everything else pretty well.
