Well today's coming youth knows mobile and computer from childhood. Yes very poor people may not be able to afford it but middle class and little lower than that as well can afford it and along with studies they can gain knowledge about bitcoin. There is one extra opportunity for people if they want to earn part time income it can be done from bitcoin through signature camping or taking up some projects and working in part time and getting paid in btc. In my country now many people are looking to start full time business related to bitcoin.
If you start to work in your spare time after 8 hours of normal work I doubt you could really do anything other that posting and coming up with a great result. I've done my fair share of "part-time" after work hours but in less than one month I was exhausted beyond the point where you ask yourself if it is worth it.
As for his vision of people getting paid in BTC we still have a long way to go.And that has no effect on unemployment.
It's juts changing the currency.
