It's largely going to come down to your budget and sound tastes. Here are some pretty good recommendations. If you don't have an AVR then you might want some active speakers, they are self powered.
We might need more info to give recommendations.
If you watch the video they discuss stuff like the robot being capable of killing someone, the example they use is smashing a human over the head with a heavy object. They keep insisting that while it is capable it won't be allowed to. Not exactly comforting haha.
Yeah looks like bullshit junk right now. Supposably you will be able to set it to do tasks at a certain time every day and it will automatically do them. Either way even if it's controlled it's pretty cheap for a slave.
Yeah I think they need to demonstrate it can work with out being teleoperated. The body idea is actually good though.
I think Asmon should get one and let his viewers control it. If it's possible to let people remote in.
