The foolishness of "natural language programming" (1978)

The author argues that using natural languages to program computers would not simplify human life, as it would increase the machine's burden and require significant changes in how we communicate. Formal symbolism is a more effective tool for ruling out nonsense, allowing humans to learn complex concepts earlier.

How does Fable 5.1 hide messages in images?

https://res.cloudinary.com/lesswrong-2-0/image/upload/v1792123168/lexical_client_uploads/rhbbcsivk5fap1xrfl2y.png
Fable 5.1, a language model, can generate artistic images using SVG and hide messages within them. The model encodes the message by altering attributes such as height of objects in the image to represent letters of the alphabet. A separate instance of Fable can recover these hidden messages from rendered images without knowing the encoding method used.
