I'm trying to think about it in terms of system dynamics and feedback loops.
This is a very solid approach, and addresses technology's impacts on society and civilisation.
There's also the questions of what technology IS and how it operates, neither of which seem to be well-formed that I can tell. I'm increasingly frustrated that there seems not to be a good philosophy or theory of technology generally. (Ellul, Foucault, Heidigger, Mumford, Schumpeter, and a few others try, though I find it weak sauce despite some good points). But definition and mechanism both address the good/evil/neutral question.
The work I keep returning to, and finding despite some weaknesses (very dry & technical) compelling strengths (excellent organisation and reasoning) is Michael and Joyce Heusemann's Techno-Fix. It's by technologists, though critical ones, and looks specifically to mechanism.
