Parent has a point from my experience - most products I worked on never really caught on in terms of being reasonably widely used. I don't think I've ever worked on anything I'd call truly essential.

From what I've seen, most programmers are indeed spending their time building experiments that have the primary goal of making money for the person that pays them - if they create true value that's more of a lucky side effect. And lots of those experiments fail.
