Millennials will over time completely change the way people think about work. Both of my sons are millennials, and their ability to multitask, and squeeze work in between their other interests is so different from when I grew up it is shocking. They have never known a world without the internet, and have been using it since they were in elementary school.
Eldest son (21) is nearing college graduation with a double major in physics and applied mathematics, but can't seem to get out of bed before noon. My youngest (18) just graduated high school yesterday and is starting college in 2 weeks working towards a degree in genetic engineering. Half the time I see him at home he is in front of his computer gaming with friends online.
Both of them can code software and built their own computers from scratch. They know how to work their butts off, but they also value their free time and work hard to make their schedules flexible so that they can enjoy their other interests (Sailing, Fishing, Scuba Diving, Video Games, etc).
I don't know how well they will fit into the working society of today, but more and more companies are trying to allow this generation to fit. Flexible schedules, work from home, online careers, etc. The amount of continual connectivity these kids are used to allows for a lot of flexibility.
I know the OP's video is meant to be a joke, but it makes a different point as well. That young girl will probably never really fit into a rigid career like banking or accounting, and hopefully she recognizes that. But if I were trying to market something online, or develop a new product, she would be someone to hire.
As I see it, the world of the future is going to be less about stability, and more about creativity and flexibility. Those that can think on their feet, and are flexible enough to take advantage of the opportunities they recognize, and the skills they learn, are going to succeed.
I look forward to living in the world they create.
