In 1712, Thomas Newcomen developed the first commercially successful piston steam engine. Mechanical work created from steam---what a game changer. This event kicked off a snowball of new innovations over the next century; the first industrial revolution. Steam powered boats and trains made it cheaper to transport people and goods. Factories sprung up, steam powered factories; food, clothes, and books became accessible. Populations boomed, and we became more urbanised and educated. Money has existed for a long time; but, before the first industrial revolution, many people still bartered with their land, livestock, and labour---a local response to a local marketplace.
The first industrial revolution was fuelled by coal, but the second industrial revolution was powered by oil. The great electrification, the internal combustion engine---my oh my, how exciting! The assembly line made goods even cheaper to produce. Health standards improved, and populations continued to grow. Cities expanded further; we had to learn how to build steel skyscrapers---vertical streets! Cars were invented; suburbs sprung up around urban populations, and big roads connected cities. People and goods weren't dependent on trains anymore, they could move further and faster, and whenever they wanted. We moved off of the gold standard after the second industrial revolution, new money facilitated quicker and more sustainable economic growth---all that wasted productivity mining gold when we could have been drilling for oil! This was/is a nation-orientated monetary solution, it tolerates globalisation rather than facilitating it.
How will we pay for the third industrial revolution? A computer age---powered by nuclear, gas, and solar energy. This emerging Internet-driven economic space is incredibly global. Money is a mechanism for facilitating transactions; transactions are ever more international. Our current solution to money isn't an international one, this is a problem. The steady state solution will be globally orientated, and digital---why should someone have to pay large fees to send, save, and receive money? I'm excited that people are working on solving this problem. Stellar, as a platform, makes a lot of sense.
