I’m just past the year Mark in being a CTO after a career as an engineer / architect. I won’t claim to be an amazing exec, but I still don’t understand how anyone could succeed in this role without having significant engineering experience. I approach this as “my turn” at playing the executive role - because I finally said to myself that there has to be someone who can code in the exec team of my next job. I intend for this to be my one and only time in a role like this - to do it well just requires more time and energy to sustain it for decades.
