I sure love to code!
I’m usually working in C or assembly writing code for micro-controllers.
It’s not hard to write software at all. It would make you a fun and low-cost hobby. :-)
That gets a hearty amen from this corner! I'm an old guy (about to turn 70) but being able to push the bits around and have the computer at my command does keep me youthful. It's really great to be in absolute control of the computer as opposed to a user at the mercy of pre-packaged software.
It's not necessarily for everyone -- but in a way it's not too different from hunting and then cooking your own food instead of relying on a prepared meal.
By the way, the very first language I learned (when it was still quote new) was C from the original, pre-ANSI book by K&R, may the latter RIP.
