why then have you become completely useless?

Job uses this question to rebuke his friends for saying such foolish things. To become useless here is hyperbole for speaking useless words. This question can be translated as a simple statement. Alternate translation: "you should not have spoken so foolishly!" (See: rc://en/ta/man/jit/figs-rquestion and rc://en/ta/man/jit/figs-hyperbole)
