I'm glad to see you writing that, and thanks. Lemme just add that I think I might be able to surprise you about aptitude to and development of "deep hacking abilities". I don't know about robotics, but C/ASM RTOS-style systems programming? I think you can quickly develop that from people with no prior exposure. I built a hiring process on that hypothesis, and months after leaving the firm we used it at, it apparently continues to be working very well.
Changing both these things would improve the gender balance.
