The top-10 carmakers by market cap make up 75% of global passenger car sales.

Tesla makes up less than 2%.

The Tesla bubble will be widely documented in history books.

I can't remember a BBC "constitutional" series this weak. The objects are presented as some sort of cipher for deep constitutional traditions, but everything is wrapped up in 15 minutes (on flags, good luck) or banal. Rubber bullets mustn't be "materials of state"...

In the Yiddish schools of the Americas, waiting til “later” to discuss the Holocaust was not an option. Stories helped school-aged children metabolize the violence to their European cousins and grow into ethical witnesses to the destruction. #sparklingsentences @princetonupress.bsky.social

All of the companies that make the software I use are increasing their prices, to account for an "investment" in AI.

I'm sat here imagining how my clients would feel if I added 30% to each invoice, because I "really got into gambling".

On 3 December a century ago, the Irish border was set for major change.

In this @rtebrainstorm.bsky.social piece, John Gibney, @difp-ria.bsky.social explores how the 1925 Boundary Commission cemented the partition we still live with today.

There was a chance the 1925 Boundary Commission could reshape the Irish border so drastically as to make Northern Ireland unviable and thus bring about Irish unity

Brett Kavanagh, his friends, and his family will be living with these images until their dying days. Unimaginable betrayal of the American creed.
Agents in Key Largo, Florida ripped this woman wearing medical scrubs out of her car as she screamed she is a US citizen. Agents cuffed her and put her in one of their cars.

In 1911 most people posed seriously for photos but little Lilly Mortensen couldn't suppress a grin. The future wife of Ludwig Dressel was about 3 years old and stands with her mother Martine Andrea Rasmussen in Copenhagen. If you go back far enough on Lillly's maternal line you run into Petersens.
