    • NY Times Opinion: Why Tolkien’s ‘The Lord of the Rings’ Endures (Dec 19, 2025)
      Tolkien’s Lord of the Rings endures because its “broken” references, layered revisions, and varying styles give Middle‑earth depth, mixing sorrow with grandeur. Grieving his son Mitchell’s death, the author finds consolation in that world’s battered beauty and its fleeting eucatastrophic glimpses of joy beyond loss.
  • Frank Gehry, RIP

    Guggenheim Museum, Bilbao (Source: Wikipedia)

    From the NYTimes: Frank Gehry, Titan of Architecture, Is Dead at 96

    Pioneering American architect, Frank Gehry died earlier this month. He is best known for landmark, sculptural buildings such as the Guggenheim Museum Bilbao (1997) — which sparked the “Bilbao effect” of using iconic architecture to revive cities. The Walt Disney Concert Hall (2003) in Los Angeles uses similar forms and materials for a striking appearance.

    Walt Disney Concert Hall (source: Wikipedia)

    He broke with modernist orthodoxy by using everyday materials and expressive, often fragmented forms; he was an early adopter of computer design to achieve complex, sculptural structures. I see his influence in Chipotle restaurants. We have two locally: one prominently features corregated metal throughout the restaurant; the other has a lovely lighted wall made of plywood with a series of holes. Both use simple, inexpensive materials to create a pleasant aesthetic.

    He also partnered with Fossil to design perhaps my favorite watch. It used Gehry’s own handwriting along with a clever display to present the time. There’s a simple artistic elegance in how it projects time: half past 8, 27 til 2, and so on within a simple rectangular frame.

    Tyler Cowen and Patrick Collison issued a call for a new design aesthetic while noting how Bauhaus thinking affected design in the 20th century. Gehry’s unique contribution to late 20th and early 21st century architecture is notable for how it leaned into organic forms, creating structures that are as much art as function. Architecture, it seems, can both serve a physical need and stir the soul.

    Gehry (as well Cowen’s and Collison’s Call for a New Aesthetic) reminds us that people and society are embodied souls. We need physical spaces. While the internet, mobile technology, and more recently AI tech are amazing and transformative, Gehry’s architecture invites us to see beauty in the places we live and in the structures we build. And the watches we put on our wrists.1

    1. Yes, I have an Apple Watch, and it’s an amazing tool but not in a particularly beautiful form. But that’s a much longer post I’ll likely never write! ↩︎

    From the NY Times: Roomba Maker iRobot Files for Bankruptcy, With Chinese Supplier Taking Control

    iRobot, founded in 1990 by three MIT researchers and maker of the Roomba (2002), filed for bankruptcy and will be taken over by its largest creditor, Chinese supplier Picea. Years of regulatory scrutiny, privacy issues, stiff competition, and the failed Amazon deal depleted revenue and left the company heavily indebted.

    This is another example of the incompetence of America’s antitrust laws (or enforcement thereof). I can’t imagine that the Sherman Antitrust Act was written to prevent American companies from buying struggling ones.

    From John Gruber:

    By 2022, the Amazon acquisition was iRobot’s lifeline. EU regulators wanted it shot down, and despite the fact that it was one American company trying to acquire another, the anti-big-tech Biden administration clearly preferred to let the deal collapse. The US should have told the EU to mind their own companies.

    This story is another anecdote that we’d be far better off trying to build things instead of reflexively decrying big business sweeping up smaller ones (particularly ones that were struggling). I’m sympathetic to Klein and Thompson’s arguments about abundance, particularly as AI technology is growing by leaps and bounds.

    Related: WSJ Opinion agrees: How Lina Khan Killed iRobot. iRobot filed for bankruptcy after 35 years when the Biden FTC under Lina Khan—amid pressure from Sen. Elizabeth Warren—blocked Amazon’s acquisition and Trump’s tariffs hobbled production. Critics say the FTC’s opposition and trade policy accelerated layoffs and a takeover by Chinese manufacturer Picea, showing how intervention can strengthen foreign rivals.
