We depart Ireland today after experiencing widespread optimism and sunny weather. The economy, arts, higher education, tech, and Bloomberg LP are all flourishing here. A shout out to Warren Buckley and our colleagues at PolarLake which Mike visited for the first time. And a warm thank you to the Irish Museum of Modern Art and the Finance Minister for hosting a lively dinner last night.

That relationship is so entwined, a hard border may be the least of the many headaches going forward. My old boss Pat Moynihan was famously quoted “To be Irish is to know that in the end the world will break your heart.” Let’s hope he got this one wrong.

And Trevor Noah weighed in on the confusion he expects from his mom using Apple’s new FaceTime feature allowing 32 video call participants in a single call:

“A whole 32 people on FaceTime? What is that? I feel like somehow that’s going to turn into 31 screens of my mom. My mom will be like “I don’t understand!” and I’ll be like “Stop calling me on every line!”
