I couldn't agree more. Before I had kids, I shared some of these "toys must have a meaning, purpose and conform to my adult-viewed ideas". After seeing my daughter play through some surprisingly emotional aspects of her life with Barbies, and my son come up with some amazingly inventive games with things lying around the house, it's became obvious how toys of many sorts can inspire imagination and creativity. If we limit all toys to STEM and adult-theme approved ideas (both fine on their own), we ultimately limit those children's development and imagination.
