It is enabled by default. One creator of English language content had their video misclassified as Spanish and people were getting a machine English dub on an English video. Support to fix it appears to be a nightmare.
Wait, do you mean it's enabled by default but the author can disable it?
If not, I wonder why I can still watch most videos in their original language (even though I'm in a Spanish-speaking country), and I only encountered this once so far.
It's being gradually rolled out to channels. Will likely hit larger ones earlier, or following some other metric youtube is following.
There is supposed to be a procedure to manually remove each language dub but it was broken (at least as of last year).
