This is an issue if it's unsupervised, but the transcription models are good enough now that with oversight then they're usually useful: checking and correcting the AI generated transcription is almost always quicker than transcribing entirely by hand.

If we approach tasks like these assuming that they are error-prone regardless whether they are done by human or machine, and will always need some oversight and verification, then the AI tools can be very helpful in very non-miraculous ways. I think it was Jason Koebler said in a recent 404 podcast that at Vice he used to transcribe every word of every interview he did as a journalist, but now transcribes everything with AI and has saved hundreds of work hours doing so, but he still manually checks every transcript to verify it.
