Grace Hopper apparently retired from the navy when she was _80_. And then went into consulting. So you’ve a few years to go yet.
But yeah, always vaguely thought she was younger starting.
(Aside, I wonder if recruiters in 1944 were already asking for ten years of ENIAC experience?)
"We shall need a great number of mathematicians of ability; there will probably be a good deal of work of this kind to be done" - Alan Turing, 1945.
You might find this talk by Bob Martin interesting - https://www.youtube.com/watch?v=ecIWPzGEbFc - it's a history of programming that isn't the usual style, but instead about this growth into existance, increasing numbers of programmers, where they came from, and the effects that's had on the industry and on programming languages.
As an example, Larry Page may have been a programmer in the very early days of Google, but it's been more than 15 years since Larry has seriously written code for a living.
As opposed to Jeff Dean who is still hacking away at his keyboard.
