Robotics

The level of sophistication of robots in the era of the Imperium Stellaris is mind boggling when compared to that of the 20th and 21st Centuries.
Robots can be made in any shape or size imaginable and can be programmed to simulate a host of responses. Due to advances in the Computer Sciences, robotic programming and construction allows for the manufacture of Androids (human-form robots) that are indistinguishable from organic humans without a bio-scan.
Several businesses and mega-corporations have turned robotics into a multi-billion mega-credit industry.
