I am well aware of that, but when the video comes with no slides and not even a summary, you can guess that they were not paying hundreds of dollars to have it professionally transcribed, and you can also guess that humans were not involved anywhere in the process (either to generate or review it) when they, say, phonetically transcribe fairly common technical jargon which is written prominently on the slide which has been fullscreened for the past minute in the video. (Is it really so hard to believe that the usual neural network progress curve has happened for speech transcription and that the future is already here, just unevenly distributed across videos?)
