Sometimes speech-to-text machine learning models give very good results, however I think the key is that:

1. It's overwhelmingly more useful than the [no text] it was replacing, particularly for the deaf or if you want to search for keywords in a video.

2. When it fails, it tends to do so in ways that trigger human suspicion and oversight.

Those aren't necessarily true of some of the things people are shoehorning LLMs into these days, which is why I'm a lost more pessimistic about that technology.
