Humans are, by nature, flawed. Robots, being built by humans, will be flawed too, but probably a lot less than humans.
I'd rather have a robot. They'd be more predictable, and I wouldn't have to listen to their stupidity all day. Plus, they wouldn't resent actually doing anything, and wouldn't raid the fridge, except to get you something.
Health care costs are out of control, and all the people that are scared it would cost jobs are probably nurses, or thinking about being one. Here's the reality though, it would create jobs, just not the jobs you gals want. Health care costs are assumed, at least partially, by companies that hire people, and when you lower them, you lower costs. That would allow them to either hire more people, or lower costs for their services.
I don't want to be in a situation where I have to subsidize nurses if they aren't needed. Health care is out of control, so anything that helps should be considered. I'm not sure these devices are the answer though, but even if they work in limited situations, it is something. And while you might not like a mechanical beast instead of a smelly, obnoxious, chatterbox human, there are some that do. Why would you object to someone having that choice, if it really works? I'm not convinced this thing will though; I'm still convinced computers are high speed idiots. But maybe for limited situations. And from there, maybe they can improve it to take on new situations.
