Only nobody cares about you.
As in a restaurant, people care about the food, not the cook.
And even if you (and I) mattered, developers of a piece of software are N, where users are 1000N or 100000000N. They matter massively more.
Oh, and there will always be programmers as long as there are money to be made, so the "without me [in particular] there would be no software" argument doesn't hold much either.
