To be fair to Jericho, he did help make Sammy a star until he kept fucking it up for himself. The rest of his run has been everything the Learning Tree gimmick is lampshading, so I guess he thinks its some great meta concept.
Also the greatest testament to Jeff Jarrett's brilliance is how he got AEW fans in 2024 to rally behind him to beat Hangman. That match was just a master class in working, not the MOVEZ definition of working a lot of people use, but the ability to get a crowd emotionally invested in what you are doing. I know the whole Punk experience probably soured a lot of folks in AEW on taking advice from the veterans, but I hope some of them are taking the opportunity to learn from a true GOAT (it likely helps that by all accounts Double J seems to be a nice guy and not a grumpy asshole).
