There have been so many weird slip ups, like that moment Adrian referred to Musk in the first person; instead of saying Elon Musk did this for you he said I did this for you.

Weird things like not being able to name 3 women; getting really flustered when Grimes and Vivian are named as women.

Weird things like Musk tweeting frequentlyexcept when Adrian is playing video games

It's possible that Adrian is a superfan to such an extent that it's made him sick in the head and he basically believes he is Elon Musk, and the tweeting timing is just a coincidence.

It's also possible that having obscene wealth like hundreds of billions of dollars makes you sick in the head, and makes you think you're the smartest person in the room when you're a spoiled rotten nepo baby whose Daddy owned emerald mine slaves in apartheid South Africa and you happened to invest your stolen wealth into the right places while stealing credit for the work of smarter people.

Call me a billionaire hating anti-capitalist, but Occam's Razor favors #2.
