> but we've spent the last two (three?) decades trying to close the remaining gap left by dragon in the voice to text problem space, and haven't much progress to show. Who says it's possible to close the gap? Humans are certainly not capable of doing perfect speech-to-text. You can sit someone down with a song recording and the ability to replay it as much as they want and there's no guarantee they'll ever be able to tell you what the lyrics are.
