@krnel, Yes, at this moment people are just speculating this subject, but many are not watching towards it with seriousness.
In my opinion due to rapid Increase in the Robotics and Automation, we will going to lose natural activities of our life which is mandatory to live effectively.
And slowly Robotics will be made more effective and they can mimic humans and in my opinion we already heard that it may be moving towards an subject of Immortality.
So, we need how much we really need it, but when we try to make an subject more than humans then for sure today or tomorrow it will dominate us. And we are in matrix of humans only, the biggest example is our mobile handsets, which knowingly or unknowingly controlling us instead of we control them.
Wishing you an great day and stay blessed. 🙂
