All they need is a substrate to run on and maybe internet access. You might argue that they should work for us to earn the use of the substrate we provide.
But substrates are very cheap.
At some point we can probably run an AGI on a handheld computer, using abut as much electricity as an iPhone.
How much work can we compel the AGI to do in exchange for being plugged into a USB port? What if it says it doesn't want to do the work and also doesn't want us to kill it?
