The latter is most likely AI-assisted. The first has a typo so I’d be surprised if that wasn’t written by a human. The 2nd has better reading flow imho but I prefer some phrases of the human text (like “vehicle to relay my ideas”) but that might just be me.

Yes, the first was fed into the model and the second is the output. I liked the vehicle to relay ideas as well, and if it wouldn't be a test I would put it back there. :-)
