This could be useful in combating fake news. In many videos especially in political news, foreign languages are dub over with sometimes nuanced translation that can skew audiences to (mis)understand the content in certain ways.
A translation lacking nuance/precision (due to being the work of machine learning) can also cause significant misunderstandings, though. I'm not sure you win or lose in that regard by switching from humans to machines.
the errors in ML translation would be systemic and less likely to be of human arbitration, which is less dangerous. Human translation could be deliberately misleading at a specific phrase in a specific interview.
