First, never trust an article that flatters you in the first paragraph and basically says someday you'll agree with us in the last.
Second. It could happen. It might not. Predicting the future is a really, really risky business to be in. Optimist OR Pessimist.
OK, risk is part of life. We don't know what's going to happen-- maybe Martians will invade and maybe owning gold will be profitable. Reasonable people see what has been and accept the fact that Martians and gold are not important.
We can observe the fact that we are so much better off than our grandparents were even as they enjoyed so many advantages that their grandparents didn't have. By studying how that happened and by looking at how things are now, it makes sense that our grandchildren will have it better than us and that doomers are idiots.
