The problem with Artificial Intelligence can be guessed by its name itself. It is the recreation of the most important gift with which the universe has endowed us humans -Intelligence. And as we all say, technology is innocent. This means the result of AI is intelligence without the burden of any responsibility. Yes, Hollywood has given us numerous ideas through science fiction to make use of AI, but it has give us the signals of warning too. Marvel movie "Age of Ultron" is one of the many examples when the technological products of even the most confident of scientists wrecked havoc in the universe.
Now it's up to your perception if you want to see it as an exaggeration, but it has been already predicted that if AI is capable of unprecedented development, it is capable of unprecedented destruction too.
Having its own brain? Learning? Evolving? Acting independently?
One of the biggest problems with artificial intelligence is that the more advanced it becomes, the less we comprehend its power. This makes it difficult for us to communicate our needs and demands to AI and ensure that we are being served in an appropriate manner. This is a major concern because AI has been evolving at an astonishing rate and many experts doubting whether or not they will ever be able to handle complex human interactions. The implementation of laws, guidelines, governing organizations, and ethical codes seem to be one answer because without these systems in place, any efforts at raising awareness about AI can truly just end up being lip service as decades pass by without affecting society significantly.
