Conflicting thoughts

From the readings and the video of Stelarc we saw, thoughts would not stop coming to my mind. Thoughts about how mind-blowing the world we live in is. I kept wondering, is technology really something that's benefiting us, humans? We've created it, we are its creators and we supplied it with power in the intention of aiding ourselves and making life easier, but now the question that's been posted and that's been popping to my head after the reading from Haraway is that, is the machine we have created become a part of us? Is it really helping making our lives better and easier? Or are our machines going to take over our world and our lives? The thought of "no separation" is very new, very foreign, and very scary.
