It did make me think - if he seems nervous under this questioning, it could be because he's actually Satoshi. Or it could also be because he's thinking something like, oh god, if this jerkoff convinces a bunch of people I'm actually Satoshi, all of the businesses I've worked so hard to found will collapse, I might be convicted of crimes around lying about it while founding these businesses, I might get targeted by any number of criminal gangs or even nation-states who will do all kinds of torture to me and my loved ones and will never believe that I'm not actually Satoshi and don't really have a secret stash of a bazillion Bitcoins.

Naturally, this journalist doesn't seem to care much about any of that, or that it wouldn't really change anything at this point besides making the life of whoever it actually is hell.
