Technology isn't just an industry - it's a way of doing things and is becoming ubiquitous. When people think "tech" they may think of sharing status updates or searching for a restaurant. What about driverless trucks (transportation), gene sequencing (healthcare), industrial robotics (manufacturing), automated warehouses (retail), solar research (energy), farm-specific yield optimization (agriculture)?
This stuff is all being driven from within the tech industry, even when it will benefit "other" industries.
