Without arguing against the points of view held by others, I would argue that the world's biggest problem is something much more basic. I would posit that the world's biggest problem is also it's most lucrative opportunity. In other words, if a person could solve it, the reward would be worth trillions.
By now I know that most of you who read this blog do not like suspense so I'll get right to it. The world's biggest problem, by far, is transportation. The ability to freely, quickly, and cheaply move from one place to another is THE constraining factor on happiness and productivity for anyone who lives and works in the modern world. Let's take a look at a few factors:
- In the United States, the average worker spends about 200 hours per year commuting to and from work. That's about the same as five standard work weeks. For many people in very populous areas, the commute time almost doubles to 375 hours per year.
- Making the arbitrary assumption that cars burn 2.1 gallons of gas per hour and there are 63 million commuters: (2.1)x(200)x(63,000,000) = 26.5 billion gallons of gas/year.
- Many people choose where they live based upon where they work. This means that the number of choices available to these workers is limited due to distance/commute constraints.
- Some very desirable areas to work, such as the Bay Area or New York City (for example), are unavailable to workers who live outside a given radius.
If I could summarize this section I would focus on two things. First, workers in general are wasting an unacceptably high amount of time and money ($53 billion/year in fuel cost) simply moving to and from work. The second is that labor is constrained from migrating to the best and most interesting employers. The latter is especially bad because it encourages disconnection between companies and their people based on the belief that good talent is artificially discouraged in flowing to a true "free market". Thus, because of geography companies assume they will enjoy a built-in advantage to retaining labor.
- Because of a lack of effective transportation workers are constrained to labor at companies within (generally) a 30 mile radius of their homes. This lack of mobility leads to social isolation of whole population groups.
- Cultural exchange between States (in the U.S.) and other countries is generally constrained. To travel more than a few hundred miles, costly and inconvenient options such as air travel must be used. Most people cannot travel this way regularly or at all. Europe and India, due to prevalent rail systems, are the exceptions.
- Due to a lack of mobility and interchange, great political and social differences develop over time. (Take a look at the differences between the Northern and Southern U.S. States dating back over 200 years)
This section reads more "dryly" than I usually prefer to write. The point I'm making here is that because people are unable to travel great distances due to limitations in the transportation infrastructure, large societal differences develop. If a person could live in Alabama and (feasibly) work in New York City, would the differences in culture and politics be as significant as they are today?
We have some very inefficient modes of travel today. Going anywhere by car, rail, or especially airplane is costly and highly ineffective. The ever-present chance for human error only contributes to this situation. So what could be different?
Many years ago a concept arose that proposed travel by a special "egg shaped" pod which would travel at fantastic (meaning 5,000+ mph) speeds through an enclosed tube. These underground pods would be moved by computer through a tube that had no air and thus no friction and would be suspended by superconducting magnets. Imagine something moving that fast with no friction and essentially no moving parts. A person could in a very real sense live anywhere, work anywhere, and travel to anyplace on Earth in about an hour or less. And because of the simplicity of the travel, the costs would be exceedingly reasonable. The change to the entirety of human civilization would be so immense that all known national boundaries would rapidly fade away.
Does this sound too fantastic to be true? It probably does, however... Think about a problem like this from the perspective of reward. Given that the person or people who solve it will become trillionaire(s), there is plenty of incentive to completely reinvent the concept and practice of transportation. Humans have always proven that when the stakes are high enough the impossible can always be made possible.
If you are interested in taking on this problem, you already have some competition*. Get to work!
