"Man cannot stand a meaningless life", Carl Jung. I've spent twenty-five years coding, solved some problems, made some money for myself, more for others, but what have I accomplished? It's unlikely it will be through a stackoverflow answer or a post on HN, but I quietly maintain the hope that maybe someday, through Free Software or otherwise sharing my knowledge and code, I might actually accomplish something meaningful. The economic value you're talking about has little meaning for me.
