The impacts in improved translation aren’t marginal - they improve people’s lives in real ways.
Advances in deep learning for NLP have also significantly improved search (Google and others) which has a nontrivial impact on people’s lives.
Multi-modal models that translate images into words have a significant impact for blind people.
Deep learning is significantly improving medical diagnosis, crop yield, assistive robotics, and many other specific scenarios.
Specific scenarios matter and again, it’s still very early days...
