I really do think that Design schools have lost their way and teach very little 'Design' but quite a lot of 'Art'. This has its place but not more than technology, culture and a host of other inputs.
Problem solving is increasingly human centred and is the reason why 'Design Thinking' is increasingly being adopted by other professions. Design is far too important in our lives, considering that we spend so much of it in environments that are human-made, to not be multidisciplinary.
Design schools must evolve to embrace the complexity of modern systems that rely on advanced understanding of technology and sophisticated human psychology. Our world today is very different from the world of Bauhaus and Design has come a long way from the early days of 20th century 'Modernism'.
