Dr. Ellul is regarded by some as an academic neo-Ludite (though that may be somewhat strong). However, from your reading above, you can see that his viewpoint on techology was pessimistic, to say the least.
He viewed techology as an irresistible force - and "technique" is his terminology for "the totality of methods rationally arrived at and having absolute efficiency (for a given stage of development) in every field of human activity." It's characteristics are:
1) Rationality (aspects of management such as standardization, division
of labor, and quality control)
2) Artificiality (technique creates an artificial world, denying and eliminating
the natural world)
3) Automatism of Technical Choice (the human has no role to play - technique
acts and people observe)
4) Self-augmentation (It changes and evolves with no help or direct intervention
by people)
5) Monism (it forms a single whole and its various components are self-reinforcing)
6) Technical Universalist (it has been made geographically widespread through
commerce - it has qualitatively taken over the whole of civilization)
7) The Autonomy of Technique (consider an industrial plant as a closed system
that is independent of the goals and needs of society in which it exists).
