On that note, here were a few of our favorites this week.

Meta vs. Amazon. One of the best agent use cases is taking care of mundane things that are necessary but annoying. One of the best utilities Amazon provides is reliably delivering mundane things that are necessary and mundane. That means Muse is better if it can use Amazon, but that’s a problem for Amazon because Muse doesn’t see ads. As I explained on Tuesday, that’s why Amazon blocked Meta’s new agent, and they can get away from it because their differentiation is rooted in the physical world. To bridge that moat Meta will need help from one specific company: Walmart.

GM Bends the Knee to CarPlay. Three years ago on Sharp Tech we had a few weeks’ worth of lively discussion of GM’s controversial decision to abandon Apple CarPlay in favor of its own smartphone software (which would afford it access to proprietary data). I wasn’t sure it would be a problem, whereas Ben was incensed at GM’s myopia. Three years later now … Well, Ben was right, GM has announced it is re-integrating CarPlay after three years of customer and dealership backlash, and I was chuckling throughout Tuesday’s Dithering laying out how and why this outcome was inevitable. — Andrew Sharp
Profiling the Profiler. This week’s Stratechery Interview was with a writer I wasn’t familiar with and a body of work I’d never seen before. If you, like me, are a Colossus neophyte, then Ben’s conversation with Jeremy Stern is a good place to start. They discussed Stern’s journey to tech and business writing, why Ben considers him “the best profile writer working today,” and, in addition to quick hit takeaways from profiles of Scott Wu, Shyam Sankar, Josh Kushner, Neil Mehta, and Jake Sullivan, Stern’s recent profile of Mark Zuckerberg. Come for a great conversation, and stay for a behind-the-scenes discussion of Zuckerberg that appears to be much truer to life than that new Social Network sequel. — AS
