Linda Yaccarino is leaving X

Have any of the people who noisily joined X to make a big impact fast actually had a big impact over any time frame? Remember when G. Hotz said he was going to fix Twitter search in 6 weeks, and then it turned out that G. Hotz is just another midwit like anyone else and Twitter search is still as bad as ever? Yaccarino said they were going to transform Twitter into the "everything app" with payments, marketplaces, and even banking. None of which it turns out was within the abilities of Linda Yaccarino.

Search is a pretty solved problem if you are willing to invest the resources to create a inverted index of all the text you want to search. An inverted index of all tweets would be pretty expensive. Creating text embeddings for semantic search would be the next stage and even more expensive.
