Resolves YES if, in my opinion, a new technology is life-changing before 2030.

Examples of revolutionary inventions from recent history: radio, television, air conditioning, refrigerators, computers, internet, airplanes, satellites, etc.

I believe that there has not been an invention of a similar caliber for the past 15 years, since modern smartphones came out. Some potential game-changers that may cause this market to resolve yes: driverless cars, flying cars, a cure for cancer, CRISPR, significant automation from AI, etc.

I understand this is a bit vague, but as a rule of thumb, if your grandma doesn't know about it then it's not revolutionary enough.
