Please don't put words in my mouth.
"I don't understand why some people propose this as inherently a bad thing."
I told you why I think they see it that way - because UNTIL we fix those other problems, increasing automation will make the lives of some people much worse.
If you would like to have a conversation about what to do with all of this information, I'd be glad to.
"I'm sure that cancer patient is ecstatic that we're focusing on keeping people doing unnecessary jobs rather than progressing with technology..."
I love this line of thought, because it's so wrong-headed. I worked in Medical Imaging - turning CT and MR data into 3D images for radiologists, cardiologists.
I didn't just make a radiologist BETTER at their job, I made it so that FEWER radiologists were needed to handle the same case load.
That's right, I put cancer doctors out of work.
I'm not saying my technology was a bad thing. But I'm saying that the relationship between money, jobs, and research is no where near as simple as you are portraying it (I suspect you know that, so I'm not trying to insult you.)
"If you can argue that a robot that makes a certain manual human work obsolete is not good for society,"
I literally helped put some of the most highly-trained people in the world out of work.
It's not just "manual human work" that's at risk.
"then you may as well argue against all technology that reduces unnecessary manual work in order to create more jobs for the less capable."
This is where you're putting words in my mouth.
I'm saying, "Technology is advancing so quickly that we really, desperately need to look at the fundamentals of our economy, because technology is turning Supply and Demand on their heads like we really haven't seen before."
The economists smirk that we have seen this before. I sincerely hope they're right and I'm wrong. 3.5 million unemployed truck drivers should make a good data point, shouldn't they?
