I actually don't think it's likely to be that great a career in the future. As more and more people speak English, it's becoming the lingua franca of the world. Many people are learning it. In Europe and some other parts of the world, a lot of people already speak more than one language anyway and rarely need a translator to manage with one another. I speak 3 European languages, but the people I deal with in the countries where they are spoken almost always speak good English.
You'd be better off if you spoke some non-European languages, so as to assist, perhaps, with refugees and immigrants in a given nation, and I think Chinese may prove very useful, but again, refugees and immigrants study the languages of the countries where they are settling, and many, many Chinese study English.
Still, studying Chinese and combining that with a business career could make for a good future.
