It is illegal to use in the EU for anything even remotely sensitive. Like, if you subtitle a movie with it and it messes up noone cares, your problem, if you're doing anything that has any legal implications, from college applications over job interviews to court proceedings, they'll nail you to the cross. For AI to be used in such domains it has to be certified and AIs certified for even a subset of these things plainly don't exist.

It's like with self-driving cars: What OpenAI is producing is pretty much on the level of Tesla's "full self driving". It's not even waymo who have proper autonomy tech certified to operate in a limited area in a benevolent (to venture capital) jurisdiction (some municipality or the other). Wake me when it gets actual approval from actual regulatory bodies actively trying to break it.

Rather than making it illegal to use, people need to use these tools responsibly. If any of these companies are using almost any kind of AI/machine learning they need to include a human in the loop that can verify that it's working correctly. That way if it starts hallucinating things that were never said, it can be caught and corrected.

I've found that Whisper generally does a better job at translating/transcribing audio than other open source tools out there, so it's not garbage.. But it absolutely is a hazard if you're trying to rely solely on it for official documents (or legal issues).

As far as promotion goes... It's open source software, it's not being sold.
