47 here , getting paid to develop since I was 16 and still it is fun and games. I really don't understand burnout concept and self imposed stress some people have. Must be just my luck.
Planning to do this as long as I can type :-)
Funny you mention "as long as I can type". Recently had back surgery which makes it difficult to sit, hence difficult to code. Got me to thinking about all the things that could cause me to stop coding... Loss of ability to type (fingers/hands lost). Loss of eyesight (though in college we had a blind developer). Inability to sit (back problems). Loss of mind (dimensia/Alzheimers). Loss of motor control (Parkinsons/paralysis). Im sure theirs more, but like you, i imagine I will be doing this until i cant...
fwiw i lost use of my right hand for a few months (it's largely ok now) and it made surprisingly little difference to productivity. i don't think anyone else noticed! turns out i spent more time thinking and less writing than i had assumed.
I've often thought this was the case, but fortunately haven't had an opportunity to test out the theory. Occasionally I've seen software development jobs where they look for the ability to type some number of words per minute. I think that is a red flag.
