64 and still crafting in C and assembly. Occasionally doing hardware design/specification work. I studiously avoided the management path my forty year career. The constant technology change is what has held my interest. A career in telecom: Metallic access -> DS0/DS1 -> SONET -> 56K/DSL -> MPLS -> ROADM -> OFDMA/LTE -> WiFi/BT/Lora/Zigbee. Never look back. I cannot even imagine the page count of standards documents, requirements, and manufacturers user and programmers guides I have read in the last forty years.

Had to come back and add. I am doing a lot more embedded python utilities in the last three years, but it is all interfacing to C based firmware on raw silicon underneath.

I have found python to be a lot of fun.
