Which of these will happen first
Human-level artificial intelligence
A self-supportable colony on Mars
"Self-supportable" meaning "If Earth was wiped out by a zombie plague then the colonists would not necessarily all die, but would have a chance of making life work, even if they missed the taste of chocolate from time to time".
"Human-level artificial intellingence" is not something I'm giving you a definition for, because you'd just argue about it. Let's assume you'd know it when you saw it. (Or not, if you were at the other end of a chat session!)
Context: AI and Mars.
