Interior Design Idea : Free Floating Stairs

To my readers, what do you think about the free floating stairs in this picture? I came across this interior design idea in my research and where I have my own opinions, I would like to get yours. My first thoughts are that it looks pretty cool, but I wonder about the stairs safety. If there is no handrail it might be easy to fall from the stairs. Also, this does not look like a feasible design concept for a home with children. On the other hand, I am drawn to the minimalism it creates and in the right setting, it would look cool. Let me know what you think.
