The closest I can find is that he just seems like such a smug asshole.
Check out Tom Scott Plus! He challenges himself a lot on that channel and pushes himself out of his comfort zone! I think it’s a great display of his humility and shows him outside of his usual role as more of a narrator on his main channel.
Some of my favorites from the plus channel are the episodes where he gives his producer a tattoo, overcomes his fear of rollercoasters, and tries to learn wrestling.
