Hi, just finishing 12th I like your enthusiasm to know latest innovations and developments in Computer Science. To list few happenings in CS,
driveless cars -- aka self driving cars, https://en.wikipedia.org/wiki/Self-driving_car,
Robots -- Boston dynamics, https://www.youtube.com/watch?v=LikxFZZO2sk,
AI assistant -- Google's AI taking like human, https://www.youtube.com/watch?v=JvbHu_bVa_g
Since last decade this field (CS) has grown a lot and its applications are integrated into various departments like BioTech --Simulating various drug formulas before actually trying them out on real animals/persons, Aeronautics & Space -- Autonomous control of flight and monitoring data read from thousands of internal sensors, Mechanical -- Automating Industrial pipelines to increase productivity and identity malfunctions of various manufacturing systems.
Bottomline is, any department you pick, CS technology can be applied to it to make it better and sophisticated.
