2026.37: Duo Threats OpenAI solved one of the most famous math problems, a Navier-Stokes breakthrough that Stratechery called technically impressive but of little impact to most people's lives, while Meta launched its free Muse personal agent, which Stratechery said dramatically reduces the barrier to entry for ordinary people looking to use AI agents. Apple also introduced the foldable iPhone Duo, priced between $2000 and $3,200, at its iPhone event. The NBA handed the Los Angeles Clippers the harshest penalty in league history for circumventing the salary cap to pay Kawhi Leonard.

On that note, here were a few of our favorites this week. 1. The Duo Arrives. Does the world need a foldable iPhone that costs between $2000 and $3,200? It’s a fair question. On the other hand, life is short, and tech is a lot more fun when we have new and possibly-crazy hardware projects to discuss — particularly when they’re deployed by Apple. To that end, I heartily recommend cleansing your palate from a week of media-wide AI angst by reading Ben’s take on Apple’s iPhone event https://stratechery.com/2026/the-iphone-duo-the-intelligent-personal-hub-apple-watch-audio-intelligence/ and pairing that with Friday’s Dithering https://dithering.passport.online/member/episode/i-phone-duo , and John Gruber’s impressions of Duo-mania on the ground in Cupertino. Also: bonus being-right points to Gruber, who nailed the name of this device back in April https://daringfireball.net/linked/2026/04/14/name-of-foldable-iphone . — Andrew Sharp 1. AI That Benefits Humanity. I loved Wednesday’s Update https://stratechery.com/2026/openai-does-math-reward-hacking-meta-launches-personal-agent/ contrasting OpenAI’s thrilling and technically impressive Navier-Stokes breakthrough with the release of Meta’s far less sexy Muse agent. While OpenAI’s tactics may in fact chill research in advanced mathematics, what Meta has assembled is free to consumers hardware and software that dramatically reduces the barrier to entry for ordinary people looking to harness the power of agents, making the AI upside a lot more accessible to the masses who don’t want to buy a Mac Mini. That’s a big deal We discussed Muse more on this week’s Sharp Tech https://sharptech.fm/member/episode/astra-and-agi-arrives-metas-muse-and-the-agent-opportunity-anthropic-and-the-revival-of-p-doom-angst , including tips for getting started with agents, and questions about whether people will actually take advantage of this opportunity. — A S 2. Closing the Book on a Catastrophe. Everyone’s familiar with the benefits of pro sports ownership and its ability to turn semi-anonymous rich guys into full blown celebrities, but Microsoft co-founder Steve Ballmer is now a living testament to the unstated risk — sports ownership fame can, in a worst case scenario, become infamy. Last week his Clippers received the harshest penalty in NBA history for circumventing the salary cap to pay Kawhi Leonard. We recapped all of it on GOAT this week https://goat.passport.online/member/episode/closing-the-book-on-the-clippers-catastrophe-and-early-over-under-picks-in-the-atlantic , including successes and failures in sports journalism, why Kawhi got off easy, and the staggering amounts of evidence that sealed Ballmer and the Clippers’ fate. — AS Stratechery Articles and Updates - Write Things Down https://stratechery.com/2026/write-things-down/ — Writing things down is powerful, for humans and for AI; what comes first, however, is what to write, why to do it, and actually getting things done. - OpenAI Does Math, Reward-Hacking, Meta Launches Personal Agent https://stratechery.com/2026/openai-does-math-reward-hacking-meta-launches-personal-agent/ — OpenAI solving one of the most famous math problems is extremely impressive, and of little impact to most people’s lives; Meta’s Muse agent launch has the potential to be the exact opposite. - The iPhone Duo, The Intelligent Personal Hub, Apple Watch Audio Intelligence https://stratechery.com/2026/the-iphone-duo-the-intelligent-personal-hub-apple-watch-audio-intelligence/ — Apple once again demonstrated the power of integrating hardware and software, but it’s biggest AI blindspot might be its belief in the primacy of apps.
