Years and years ago I built my own 16 bit computer from the nand gates up. ALU, etc, all built from scratch. Wrote the assembler, then wrote a compiler for a lightweight object oriented language. Built the OS, network stack, etc. At the end of the day I had a really neat, absolutely useless computer. The knowledge was what I wanted, not a usable computer.
Building something actually useful, and modern takes so much more work. I could never even make a dent in the hour, max, I have a day outside of work and family. Plus, I worked in technology for 25 years, ended as director of engineering before fully leaving tech behind and taking a leadership position.
I've done so much tech work. I'm ready to spend my down time in nature, and watching birds, and skiing.
There's a huge difference between giving a child unrestricted access to a firearm, and taking them sport shooting in a controlled environment. I've helped with beginner shooting courses for kids in scouts. There is an adult with each kid, one round loaded at a time, etc. You can similarly control the environment hunting by using blinds, etc, where you oversee the use of the firearm, loading of round etc.
I'm not big into shooting, but from a safety perspective there are ways to hunt and sport shoot with kids in a very controlled way.
