Like any domain in applied AI, there will be a lot of approaches that miss the mark, or are simply stepping stones to better approaches. There are thousands and thousands of papers on language modeling, but we only needed one superior approach (GPT) to change the game entirely.
The search through any cutting edge problem space is messy and full of failure, and that's fine. You only need one breakthrough.
