When a chatbot gets something wrong, it’s not because it made an error. It’s because on that roll of the dice, it happened to string together a group of words that, when read by a human, represents something false. But it was working entirely as designed. It was supposed to make a sentence & it did.

I cannot tell you how many tech journalists at prominent media organizations do not understand this
Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

“There are few things more dehumanizing than being told by a machine that you’re not real because of your face"
For the last month, I've been speaking to people living with facial differences and disfigurements about how face verification tech is failing them. Spoiler: things aren't going well

When Face Recognition Doesn’t Know Your Face Is a Face
An estimated 100 million people live with facial differences. As face recognition tech becomes widespread, some say they’re getting blocked from accessing essential systems and services.

Some early computers, e.g. ENIAC and at least one IBM model, didn't store numbers as binary, they used a method similar to an abacus, with ten binary flags to represent the digits in each "column" (e.g. units, tens, hundreds, etc.) of the number being represented.

1/ A longtime Wired editor just wrote a mush-brained essay about how he totally missed the political rot of Silicon Valley (& still doesn't get it).
But in the late 1990s, a Wired journalist warned of a toxic ideology bubbling up from tech. Paulina Borsook has largely been erased. Let's change that
