It’s useful in some situations, but they often tend to be the situations where it’s least needed. There’s plenty of languages that MT is very bad at translating (to the point of being counterproductive), and a lot of those languages are natively spoken by people who don’t also speak English. MT is quite bad at translating Hindi, but that’s not so bad because English is (relatively) quite common in India. MT is absolutely terrible at translating Indonesian, which isn’t great for Indonesian trade, because English is rather uncommon in Indonesia.
