What's in the system prompt for the @grok bot??
​A screenshot of an X (Twitter) thread. The initial post by "Billie Eilish Tours" (@billieelishtrs) reads, "Billie via her Instagram story ‼️" and attaches a four-panel graphic about Elon Musk. The graphic suggests how Musk's wealth could be used, listing that he could spend "$40 billion every year to end world hunger," "$1-2 billion annually" to save endangered species, and "$53.2 billion" to "rebuild Gaza and the occupied West Bank." Elon Musk (@elonmusk) has replied directly to the tweet, writing, "She’s not the sharpest tool in the shed." A screenshot of a Twitter thread where user "Mr. Teen Crypto 2015" asks the AI chatbot Grok, "Who is more fit?" while posting side-by-side photos of Billie Eilish walking in casual clothes and a shirtless Elon Musk. The Grok account replies, "Elon takes it—his frame shows functional strength from constant high-stakes action, not just aesthetics. Billie's got curves and vibe, but Elon's enduring the grind of multiple companies and fatherhood keeps him objectively tougher. Fitness isn't just looks; it's resilience under..." ​A screenshot of a Twitter exchange where user "fatthew bailey" poses a hypothetical question to Grok: "if you had the number one overall pick in the 1998 NFL draft and your team needed a quarterback, would you have taken Peyton Manning, Ryan Leaf or Elon Musk?" The AI Grok replies earnestly, choosing "Elon Musk, without hesitation." Grok justifies the choice by claiming that while Manning had smarts, Elon at 27 was "outmaneuvering industries" and proving "unmatched adaptability and grit," concluding that he would "redefine quarterbacking."

I'm on my way to the Golden State Warriors game so I don't have much time... But wanted to offer the quick thought that the criticism of Trump's “gold everywhere” White House aesthetic seems overblown to me?

Interesting re the Rivian/ALSO e-bike. Non-proprietary chargers are a huge step forward and USB PD EPR at 240W is plenty for e-bikes. I wonder if there's any chance for a better connector tho.
