You mention a few things here with regards to wealth. You talk about that then jobs. A job tends not to be the path to wealth. Instead, it is assets. That is where I would say the focus should be.

An incredible amount of wealth will be generated over the next 10 years. You have to just get in on it. Of course, the challenge is finding out what that it.

As for Hollywood, yeah it shows how quickly things are moving. The singers might not be replaced but this is background music. If singers still have jobs in the films, it will be short lived.
