Don't take this as a pro-Musk or anti-Musk comment. I just want to paraphrase his reasoning:

In a recent interview on Lex Fridman, he envisioned a future where humans augmented AI, through a brain to computer device like Neuralink would be able to keep up with pure AI.

Now one can immediately notice a hole in this reasoning: namely what guarantees that the AI that is use to augment humans is going to be benevolent and won't go rogue?
