Computer hardware is what its called
In my lifetime Face Book has most hurt me. Hackers hacking my account. Saying things I never said and pretending to be me. It disconnected me from my freeinds literally. They never wanted to talk to me. It really was sad.
The answer is c. Steve Jobs and Steve Wozniak.

Hope this helps
