The Halting Problem: what this star will be

The Halting Problem is a star on the Constellate sky: placed by meaning, named, and connected to the stars around it. This is the short form of its post: the line it carries, the area we colour Computing, and what stands beside it today.

The line it carries on the sky: No program can decide if every program will stop.

What stands beside it

The stars nearest to it are Alignment, Gödel's Incompleteness, The Hard Problem of Consciousness and Infinity, and Alignment, Infinity and Embeddings are already open to walk. When The Halting Problem opens, the conversation will land it among them, with a line drawn to each idea it touches.

Ask for this star

Every star is lit by demand. Ask for The Halting Problem and it moves up the list; when it opens, this post becomes the full essay. The open stars beside it can be walked today, and the first concept of every course is free.
