In terms of complexity, certainly. When you look at the assembly code from the inside, with something like IDA it branches out infinitely. In terms of fun. I'm not so sure.

Say, finding and replacing some part in an aviation radio is a lot more fun, than spending time annotating insides of some executable.

I think that depends rather on who you are and your interests, to be fair - as much as I'm a fan of the former, the latter sounds like rather more fun.

True. But a lot also depends on the context. When you are dealing with some binary, unless it is antique, most likely you are doing something nefarious. Like obliterating somebodies license check. And while there is certainly a feeling of some elation, when you are finally succeeding, it can't compare with the joy you feel, when some electronic component is coming alive after you've finally fixed it.

Thanks for that - it's something that is actually pretty close to my heart but I hadn't thought to throw into the comparison.
