Believe it or not, I appreciate and relate to that sentiment.

But after spending roughly one year acquiring knowledge related to this work, I feel I can say with a fairly high degree of certainty that this dataset alone is enough to train a model that will achieve "world class" status in some area. Writing books, perhaps.

Which part of my logic do you feel is mistaken, and why? I am actually quite interested to hear thoughts from someone who is very pedantic about such things.

I don't think you are mistaken, I guess it's just that there is just so much information you can convey in a tweet, when I read "world class GPT model" I understand a model that will beat (or equal) on general NLG, which is not what you meant it seems.
