I spend many years of my life writing software, much of that for embedded controls for commercal kitchen equipment. I still get excited when new systems are turned on for the 1st time. It is exelerating and causes the hair on my neck to stand up.
I mention this because a young engineering stopped me and asked if I had a few minutes to see something. She had turned on a new control … and it worked. She was excited, and it reminded me of those early years. Making something new is so exciting. It still runs through my veins and is part of my DNA. I love watching another generation of engineers experience this euphoria.
