I think learning to program will change lives in Africa faster than any other thing. The ladies are quick on their phones and got that sorted out; but if you want to get OUT and travel, if you want to have a rich life and accomplish things, then there's nothing better than being a master of tech, and EOS is the best tech to learn in 2019.
If it was me, I would get my hands on ANY PC I can find. I don't care if it's 10 years old, I don't care if it's not pretty 😉 All it needs is CPU, a display, a powersupply, a flash drive and some RAM on a motherboard. You can put it in a milk crate, and control it with any kind of keyboard/touchpad. Learn to use a PC, and it can run both Linux and Windows 10. Build it yourself and understand how it works…
