The single most reliable way to come to a loathing of the software development process is to engage in it for a living.
It’s shocking to me how many of them are deeply passionate about dentistry and teeth/gums/etc. This may be a situation where I tend to mostly work with successful happy dentists, but the same bias may exist w/ you and developers.
I'd say it still is a lot of fun as long as you optimize for the fun bits and not the highest salaries.
But I agree in the sense that working as a developer is very different from coding-for-fun
To me they are very disconnected activities.
At work I don't even write code like 60% of the time.
