To be fair that industry has always had fabrication and dishonesty as ongoing issue long before AI.
Also I really question what this litmus test would check for and how accurate it is. Just the other day I read an article that frontier AI models outperform law students and that professors could not distinguish it from a human written ones and actually flagged human written ones as AI.
I do view this as overall positive progress in that the ridiculous barrier to entry and wasteful formality is being eroded and as will the professions that benefited from that moat will open it up to the general masses.
I personally believe we should be celebrating the universal access to knowledge and printed words
