It's unfortunate future-planning. It's impossible to know what the future holds but there is some level of precedent to help decide. Although with no guarantees, a job that has been around for hundreds of years is a bit more likely to stick around than a new job field that was just created 2 months ago. I'd go in debt to become a carpenter before I went in debt learning a JS Framework, as an example.
