A person holding that every social, political, economic and cultural change is inevitably driven by the development and diffusion of technology is a technological determinist.

Technological determinism treats technology as the prime mover shaping society and its institutions.

Believing culture rather than tools is the decisive force names a cultural determinist, which reverses this causal claim.
