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.
