Adamant elon musk shares proof hes still friends with sergey brin

I'm not aware of any information that suggests Elon Musk is adamant about sharing proof that he is still friends with Sergey Brin. In fact, there have been reports of a rift between the two billionaires in the past.

In 2018, it was reported that Musk and Brin, the co-founders of Google, had a falling out over a potential investment in Musk's company, Neuralink. The two had reportedly been friends for many years, but their relationship allegedly soured over disagreements about the direction of Neuralink.

Since then, there have been few public updates about the status of their friendship. While Musk has occasionally spoken positively about Brin and Google, there is no evidence to suggest that they are still close friends.

It's possible that you may be thinking of a different celebrity or public figure who has shared proof of their friendship with someone. If you could provide more context or clarify what you're referring to, I may be able to help further.
