Humans have changed a lot and got into better conditions due to machines. Machine was invented to meet the basic and required needs of a man. The 21st century is the generation of technology.
Man is the actual inventor of machines. Our day-to-day operations are based on machines itself. We can't do any specific work without machines. Some tasks are really impossible for a man to do, where as they're possible for a machine, Vice - Versa.
We've grown extremely dependent on artificial intelligence. Man is both the creator and destroyer of machines. Humans have the capacity to grasp, learn, and create things and are extremely multi-talented. Whereas machines are not, because it's functions are limited. Machines don't have emotions, which means they don't have emotional intelligence. They only do the work assigned to them.
