He's an 80 year old entertainer. He has an act, which he mixes up a bit for each audience. But most are largely the same. Similar to a standup comic, or musician. He did do quite a bit of targeted bitcoin stuff in the talk, but he wasnt always in his comfort zone, and relied on what he has picked up. He wasnt that bad, more like a year 1 student picking up the basics. He kind of tailored about 50% specifically to a sophisticated bitcoin crowd, and just about survived. A bit like asking your grandpa to go give a talk at a quantum physics conference. He made it to the end, without looking like he wast trying to make to the end, at times fell back on his prepared patter. He got some of the big items correct. But has yet to find out about shitcoin scams. Maybe he can learn.
