And they absolutely will not stop! Ever! Until you are dead.
It’s fair to ask, if NASA is getting 50% of the world’s funding and the rest of the world is going to the Moon, why is it unreasonable to expect that we would go as well? There are two possible answers. Perhaps the rest of the world has an unrealistic impression of the complexity of the problem and their own capabilities. Or, perhaps our own space agency has turned into a bureaucratic morass that is incapable of finishing large projects without spending ridiculous sums of money. For sure the former is a factor, but there is plenty of evidence that the latter dominates.
I think we are victims of the unstoppable hand of history in this case. NASA built the pyramids. They drove the golden spike. They defined the nation for all future generations. But once they were done, we could not throw the heroes out on the street, and we certainly could not let them keep the checkbook. So everything that has happened in human spaceflight since about 1970 has been one big retirement party and career transition program. It’s a colossal waste of time and money to pretend otherwise.
But hope is not lost. There are many bright and hungry people out there who can make the next giant leap given the right support structure and incentives.
Agreed. The right incentives applied slowly could fix the carbon problem efficiently and with minimal disruption, at least in the United States.
I am already lighting my house with LED bulbs, taking the bus, and turning off the AC. That reduced my annual consumption by probably 20 GJ. But 35 years down the road I want to be able to harness more energy than is available to me today, not less. More computers, faster and farther transportation, 3D printing, stuff I can't even imagine yet, it's all going to take more energy no matter how efficiently we use it.
To be or not to be, that is the bottom line.
