Speaking of which. What happens when every computer in the entire planned is operated by a black hole?

I can imagine the tech support:
[dailing]
Tech: Technical support, how may I help you?
Caller: Yes, I have a SLIGHT problem here. My computer just fail and the black hole has just swallowed up my computer and is beginning to take my house along with it. How do I turn it off? Is there an off switch?
Tech: What off switch?
I can't imagine a future like that. If they plan to make a computer like that, I hope they make it in a place far far away - like a 1,000 light years away.
