The 1964 LBJ “Daisy” ad warned how recklessness could end in catastrophe. Trump’s volatile, impulsive geopolitics revive that same fear: power wielded without restraint, assuming the worst won’t happen—until it does. youtu.be/riDypP1KfOU?si=HL2Z…

History warns us: Guns of August & Clark’s Sleepwalkers show how great powers drift into crises through miscalculation and bravado. The Greenland situation feels uncomfortably similar—small moves, big symbols, and Congress leaders assuming it will all work out…until it doesn’t.

Quiet magic of Tokyo’s unplanned, human-scaled backstreets—where cars are welcome only as guests, weaving their way gently through pedestrians and cyclists. Streets like these remind us that vibrancy and human connection are at the heart of every truly liveable, lovable city.

I’m no longer active here. I truly miss the old Twitter—the spirited debates, the exchange of ideas, and our shared concern for the future: the climate crisis, inequality, and more. Sadly, X isn’t that place anymore. I’d love to reconnect on the other side. Come join me there!

Back in Japan after traveling through my home region in rural & urban Germany, I feel energised. Our shared challenges are clear: foster biodiversity& regenerative sustainability, build resilience, strengthen local democracy, cut energy use & advance equity thru mutual learning.

It’s time to make the journey. I loved our urbanism community here & over the years I met many of you in person or virtually. Twitter was a good public square. However, with an enemy of democracy at the helm I am pulling out. Would be nice to see some of you on the other side!

I met recently with the gentlemen of @MeMyselfDisaste who are travelling the world in order to document and share cutting edge disaster response solutions for an age of accelerating change. Here’s me, briefly talking about an evacuation park in #Tokyo. youtu.be/THGcGKKmvXg?feature…

Remove the last 10 seconds with the narration and this is a new urbanist ad. ~20 years ago GM tried to sell Saturn Ions and Vues and accidentally showed us how much better urban life would be without cars. --> youtube.com/watch?v=e_oWmY_m…
