Concepts
Every concept guide we have written.
What is artificial intelligence? Machines that learn, explained
A broad name for a family of narrow tools. The systems in use today are extraordinarily good at finding patterns in data and hopeless at knowing when they are wrong. Treat the phrase as a label for techniques rather than a mind, and both the hype and the fear get easier to place.
What are posthumans? Beyond human, explained
A name for a question rather than a thing. Every road to the posthuman runs through technology that already exists in a laboratory, and through choices about who gets to use it. The interesting part is not whether we would still call the result human, but who decides.
What is a wormhole? The shortcut through spacetime, explained
Hypothetical, unstable and probably impossible to hold open, which is exactly what makes it useful. A wormhole turns an impossible journey into a decision, and that is why science fiction keeps reaching for it.
