What is the sole thing humans can currently do better than computers?

"Emotions" is the sole thing humans can currently do better than computers .Human is "Emotionally Intelligent"And computers are "Artificially intelligent"

That's the key difference because Human logic is often highly illogical. 

compression, having feelings ... a computer is a machine which we will utilize to help us with our work  

There are three types of work that humans do really well but computers cannot (yet):

1) Unstructured problem-solving: solving for problems in which the rules do not currently exist. Examples: a doctor diagnosing a disease, a lawyer writing a persuasive argument, a designer creating a new web application.

2) Acquiring and processing new information, deciding what is relevant in a flood of undefined phenomena. Examples: a scientist discovering the properties of a medicine, an underwater explorer, or a journalist reporting on a story.

3) Nonroutine physical work. Performing complex tasks in 3-D space, from cleaning to driving to cooking to giving manicures, which is thought of as relatively low-skilled work for humans, but actually requires a combination of skill #1 and skill #2 that is still very difficult for computers to master.

Wow, again a tough question you have there. I think the ability of decision making during difficult times.

Human at times may derail from logical conclusion whenever emotionally charged. Hence the computer had become his / her companion. However that companion's logical thinking is far exceeding its creator.

In any case, it is the human's sole thing that he / she created such companion ever.

Emotions Never TO be felt by IRON

It's the human's ability to be flexible and unpredictable in different circumstances. Computers are programmed, hence it can only process things which are under its scope or within the data encoded to it while human can extend beyond it and think out of it. 

human is not Programmed as a computer

the mind of human gives him the ability to think, Imagine, and take a decision .

Computer cant operate with the help of human.

to give more information to Compute's memory means decrease the space of it, decrease the performance speed.

to give more information to human's Memory means increase the development of Brain and increase the performance and knowledge of mind.

Human can develop himself, computer cant

Human has emotions, Computer hasn't.

The best sole thing human can do is controlling the computer itself as man is the inventor and the one runs all its programmes. Computers work fster than human being but cannot think on its own as man does. A computer guided roboto can pick up materials and throw to other side in the industries to make the work easy and much faster but if a man comes on its way it will pick him up and throw him to death but man in its place can stop the man from death. Ofcourse computers made our work easy and much faster than man do and stores unlimited files which can be accessed in seconds unlike good olden days where it was a very tough and time consuming work, But we cannot forget that all this made possible my human intelligence and human brains. 

A smile can create a lot of positive changes in Personal relationship and its chemistry where the computer fails to achieve it.
