The honest position on machine translation is that it is genuinely useful and genuinely insufficient, and that both halves of that sentence matter.
Where it holds up
Routine correspondence, internal drafts, getting the gist of a document before deciding whether to have it translated properly.
Where it does not
Contracts, medical information, anything legally binding, anything culturally loaded, and anything that will be published under your name.
The practical rule
If being wrong would cost money, reputation or safety, a human reviews it. That is not protectionism; it is the same rule you already apply to accounting software.
