Not sure what your definition of 'Design Thinking' is.
Design Thinking isn't about people thinking "that they can just come in and design user interfaces, etc. without really having an expertise in the particular field."
It's a problem solving approach using UCD methods amongst others and working with experts in the field to come up with solutions and ideas to a given problem space.
Key thing is you work with the people who are experts in the field, for example working with medical experts to design a new health related application etc.
