It's not wasted at all - people are learning and configuring, tweaking and optimizing their use of a computer. I for one really like the fact that Manjaro is an easy Arch for me. Is it wasted creativity now that I can focus on non-distro work since I found my distro?

Besides, who is the author to tell people to not waste creativity. It's remarkable to have this audacity. Even the notion of "wasted" creativity is just not nuanced.
