In Mainland China to get ahead you need to learn to say a bunch of stuff that nobody believes in, e.g. Maozedong Thought in high school/uni exams. Like political correctness in the West, except few people take it seriously. Ma's points were an example of this: focus on education, focus on AI helping us understand ourselves, focus on growing creativity, focus on what we can do to help the Earth, focus on automation freeing up more time for leisure. Non-controversial platitudes that nobody can really disagree with (at least not in China). Musk completely misses this, and goes out saying all kind of stuff about aliens, superintelligent robots and "biological bootloaders" that sounds completely bonkers to somebody not caught up in the hype (or somebody who actually works with ML). Ma catches on to this and has a field day hamming up his presentation, realising that this game is something Musk is completely incapable of playing. Just imagine how absurd it would be if somebody stood up at Party Congress and started talking about aliens; that person certainly wouldn't be presenting at the next Congress to say the least.
