Most prominent of such speculations being made is regarding the effect of Artificial Intelligence. Well, this is something too much to get worried about. It is certainly not going to happen shortly.

Moreover, the level of sophistication requires making the technology replace human brains, specifically for coding too higher. Yes, the developers should look for smart ways of coding, rather than depending upon the manual modes. In short, if the technology is something developed by humans (coders to be specific), its future can also be decided by the same. So, unnecessarily worrying is worthless!
