I don't think there are that many people who own these things, and of those that do, the ones willing to buy an ISP programmer, compile this and program it are probably a fairly small percentage.
Earlier today I fixed my shoe. It was coming apart, and so I grabbed some baling wire someone had used to put up a long-gone advertisement, cut it into a kind of staple, forced it through the shoe in the appropriate places, crimped it, and cut off and crimped the ends to avoid risk of injury. Probably nobody else will ever wear this shoe. Did I fix my shoe narcissistically?
Tonight I will make dinner for a friend of mine, probably a kind of omelet with some salad. Only the two of us will eat it. Are we eating it narcissistically?
I have written a shopping list in order to make the dinner. Probably nobody else will read the shopping list. Was writing that shopping list a narcissistic act?
I don't think so. I think you're suffering from some kind of pathology that devalues anything done for pleasure instead of in service to other people. I recommend that you abandon this ideology and struggle against the pathology that makes it seem appealing to you, because it will kill you.

However, in seriousness, I love this. Coding things in Assembly is excellent, and a great way to learn loads of useful and interesting stuff which you wouldn't have come across otherwise. Keep up the good work!
