Do you tend to suffer from mental overthinking? Some people keep ruminating over a casual remark they made days ago. Others lie awake all night because of a hurtful comment from someone else. They drain enormous energy through endless pointless obsessions, regrets and self‑criticism. But why does this happen? More than two thousand years ago, a group of Roman philosophers figured this out: the...

Anthropic has announced that all text generated by Claude will carry invisible watermarks. Many people’s first thought: plain text is just a string of discrete characters. There are no hidden pixels like in images, nor embedded metadata. Copy and paste it into a notepad, and all you get is plain black text on a white background. So how do you apply an indelible invisible watermark to a block ...

Why did Jensen Huang drop a staggering $12.9 billion to acquire a seemingly free website? NVIDIA’s latest blockbuster acquisition — the full purchase of Hugging Face — has left many industry observers confused. The platform generates merely $150 million in annual revenue, yet NVIDIA paid over 80 times its sales multiple to take full ownership. Hugging Face is no tech giant with proprietary har...

Suppose a year ago, you and I fell in love. I told you I would love you forever, and that we would never part. Soon after, however, I fell gravely ill. Every single organ in my body was replaced, and I lost all my memories. I no longer have any idea who you are. Would this person still be me? This question is deceptively hard to answer; it is practically a paradox. Philosophers have debated va...

What would you do if you meet someone better after falling in love? This seems to be a situation that can easily happen, and everyone has their own take on it. Long ago, Socrates offered us an answer to this very question. As the story goes, Socrates’ students asked him what true love really was. Instead of giving a direct reply, he led his students to a wheat‑field. He told them to walk thro...
