NASA X Revolutionary Evolution - ERA

What does it take to change the world? Historically, change has usually been slow-moving and methodical, taking hundreds of years for even incremental advances to be seen. But over the past century, things have shifted, and that trend has reversed to the point where some forms of change now come at breakneck speed. Just look at our personal computing devices as an example. Our cell phones, laptops, tablets, and other devices come out to great fanfare one day, only to be labeled as obsolete and clunky after only a few months. In our consumer-driven world, that type of fast-moving change is okay, but when it comes to building large-scale, long-term items like cars, buildings, and aircraft, the process is slowed down to make sure those items are as safe and reliable as possible. This disciplined and deliberate process can be seen clearly in the aircraft industry. Before new technologies are implemented, they are first tested and retested for many years to make sure they will perform perfectly every time.
