I at some point will be unemployed, but that is because my robot army will be taking care of everything for me, including running any dirty hippies off my front lawn.
Seriously though, what is there to worry about? Being unemployed? Do your own farming and make your own stuff. Prices for tools and automation are collapsing. It is getting to the point where for the cost of one decent large shop power tool or two at 1980's prices you can outfit most everything you need for a full garage workshop/maker space.
If you can't make or fix stuff or don't have the magic social skills that get people to work together you should be worried. You will be on welfare and not have much opportunities beyond that in the coming decades, but then again with the prices tanking on all tech and finished goods that means basically a lower-middle income lifestyle, which these days isn't all that bad.
