And it’s not “just” because he sounds like Elon. There have been multiple occasions where Adrian has said “I” referring to Elon. Obviously people slip up in speech, but also obviously some people have pseudonyms.
Adrian has lots of in-depth knowledge of Tesla/SpaceX, shows up in the same circles as Elon constantly, has an obscene Twitter addiction (i.e. just participated in a 10 hour live audio chat), defends Elon at every chance including in deeply weird/personal ways like “you are such an amazing father Elon” on pictures of Elon and his kids.
It’s all quite weird and people are absolutely justified to be curious what the fuck is going on.
