Yes, anyone can find anything enjoyable or terrible - but the point I was trying to make was that most hackers enjoy bug fixing by nature and Geohot seems to be exceptional that he despises bug fixing as mundane.
Hackers enjoy bug finding or simply building new stuff. Why would they like fixing bugs? Why would any developer enjoy it for that matter? Yes, it's something necessary that all developers should know how to do, but that doesn't make it enjoyable.
A nagging bug is ultimately one more thing you don't understand. I don't know about anyone else but as someone who loves to take apart things I don't sleep well when I find there's something out there that I don't understand. Besides bugs are a given if you're building something new and if you don't find them interesting you're not going to fix the most challenging ones. If you ever followed Linux kernel development you'll find many hackers enjoy fixing challenging bugs.
