As a doctor, you could spend three months looking at tens of thousands of MRI images or give that to a computer, for the computer to process, if you have this smart computer vision model that's trained to detect cancer and images.
There is a Swiss hospital doing exactly this and they start to be quite good at it.
I think it is importend to progress and robots are awsome. I can see that it might be scary for some people as they could loose their job, but if you see the bigger picture robots and automation is what enables us this great and comfortable life. I really don‘t feel like hunting every day and sleeping in a cave... :P
There's no denying the fact that robots will do things faster and make us comfortable, but what happens to those that'll loose their jobs to robots? That's a major disadvantage.
