IMHO think it is something of a looking back / looking forward situation. Looking back, the Twitter brand has indeed accumulated massive goodwill. Looking forward, it would appear that some kind of LLM is replacing search (bard.google.com replacing google.com; chat.openai.com replacing bing.com). Elon has been very busy establishing the new https://x.ai/ as an alternative LLM "to understand the true nature of the universe", with no fewer than 11 new key executive technical employees this July. It is clear that looking forward, Elon has a hybrid vision of Twitter morphing not just into a WeChat clone, but going well past that and potentially knocking on the heals of ChatGPT/Bard as the next obvious incarnation of search.
