As technology advances (Automation → Robotics → AI → Unmanned Systems), ROBOTIC, AI, and AUTONOMOUS variants of buildings unlock — little staff, high output.
Autonomous buildings need internet, robots, CHIPS and AI CHIPS. AI chips are made from regular chips (AI Chip Foundry) — a prerequisite for every AI or autonomous building.
Automation creates unemployment; to counter it there are the UNIVERSAL BASIC INCOME (set with the budget slider) and Unemployment Benefits policies. Autonomous military vehicles also need a NUCLEAR BATTERY.
