The complexity will always live somewhere. Just because you are a frontend developer, and GraphQL magically makes your life easier, it doesn't mean that complexity is just gone. That backend you're so dismissive of is what powers your site/app, and it needs to be developed and maintained, and has to be performant etc. etc. And yes, GraphQL makes backend significantly more complex, fragile, and prone to significant performance issues.
