More software than hardware, but I share the same wonder at Kubernetes. I love the whole concept of: "this is a big blob that runs your stuff, don't worry about networking and some other server-type considerations, just run your apps and there's a bunch of magic"

It's a little sad to see my previous career disappear, I'd love nothing more than to manage some VMware clusters running Linux VMs for the rest of my life, but technology moves on. It's forcing me to become a coder and manager rather than sysadmin.
