I don't think 'originality' should be the goal of any language. Being novel for the sake of novelty inhibits effective communication, it doesn't enhance it.
Originality is a virtue if the language really has a better way of solving certain problems that people face. Even if it has merely a different way of solving certain problems, that may be very worthwhile, because the different way may in fact turn out to be better.
But novelty just for the sake of novelty... yeah, not so much.
