I think you do. Have we ever been successful at slowing down technological efficiency?
>If that comes to pass, then what people will do with that technology, and what will change as a result, will be up to the people who are alive at the time.
If it is inevitable that technology will be developed, it is also inevitable that it will be used, and in turn, further technology developed. Technology is an arms race. You can't opt out once you've started. If you do not employ the same technical progress for whatever-- propaganda, profits-- you will lose.
I know you're not posing it as a problem or solution, but I believe pinning it completely on "it's how we use it" is not a valid tactic either.
