Point #4 is like decrying the invention of the printing press. Destroying bottlenecks in people's ability to communicate with one another isn't a bad thing even if it puts the middle-man out of a job, but I doubt it even does that: people are still going to want a real human to translate anything that was important enough to translate in the past; AI just means we can afford to translate lower priority stuff too.
