Machine translation certainly has improved a lot, but still has the usual AI issues- namely that the AI confabulates details in places where a human translator would realize that something is unclear and refer to context, other parts of the text or external research for clarification. A common example in Japanese to English is that Japanese often omits pronouns, while the English version of the sentence requires "he"/"she"/"me"/"you" to be grammatical. A human translator can check this, but AI will often autofill whatever is the most common in its dataset, which could be completely wrong in context. So I think the risk with machine translation is that it can seem reliable and trustworthy 90+% of the time, but if you have no ability to read the original text and compare, you're rather quickly going to get caught out by something that looks like a professional, clean, correct translation, but is a total misrepresentation of what was actually said.
