The fact that something can do something better than me doesn't make much difference. The problem there is the comparison. I like doing things for their own sake; I like knowing things and the process of attaining said knowledge. Making something is satisfying in a way that buying it isn't. Why do people make their own furniture? Why do people restore old cars? Why do people do pretty much anything? Most of what we (on average) do for work is kind of meaningless in some sense - it's an ends to a means. And yet, sans that, people still DO things.

Because we want to. Because we desire to.

I'd rather have MORE time to spend doing the pointless things I LIKE AND ENJOY doing than MORE time doing somewhat pointless things for companies.
