Since we are in the Fourth Industrial Revolution, AIs are starting to be known by us. It is most likely happen that they will replace humans jobs in the future. I anticipate that it will be a boom when we reached the Fifth Industrial Revolution.
None can replace human Brain. Humans are creating all technologies but no technology is equal to human brain. So technology can't replace human. The technology getting advanced just because of human brain.
Artifical intelligence cannot replace human beings because they are made by humans to make life easier. Advance in technology sees more use of AL and machines but still jobs will be created for persons who will maintain them.
