A while ago, many people speculated that Musk and CZ had a bad relationship, and that CZ was easily offended. Judging from their recent interaction, their relationship seems quite good. CZ replied to a post from a rumor-mongering account, and Musk agreed in the comments. Interestingly, @cz_binance seems to be using Grok. It has to be said, asking Grok about Twitter rumors is incredibly convenient.
