Ask HN: Am I harming my career prospects by working in computer architecture

I'm a SW engineer by trade, having worked in the area of hardware-software interface for the last decade. Recently (last 1.5 years) I've a new role that is leading to my contributing more at the hardware architecture level. I'm really enjoying it but worry that I might get pigeon-holed or it might work against me in the long term. Anyone else been through this sot of thing? Any recommendations?
