Just a confusion that you mentioned KubeCon 2022 of Valencia , Spain in the beginning but mentioned all the talks an used images of KubeCon Detroit.
So please review your blog.
Actually, Kubecon was held in Valencia, Spain{europe} between 6-20 May. And then it was held in Detroit {North America} 24-28 OCT. Both of these events were held this year only. That's why I have used pics related to both of the Kubecons.
