Yeah, I remember reading an interview with one of the few big demosceners, and they said that to compete in the highest leagues, you need editing tools to build these impressive scenes.

After all the most talented musicians and visual designers often were not the same people, and every artistic pursuit involves a lot of iteration.

To be fair groups tended to build the tools themselves, not to take away from their achievements, but once the tools are done and public (like the ones you shared), a lot of the challenge and point of competition is gone.

Tooling also tends to create a moat between 'users' and 'developers', the former of which lack the low-level knowledge to transition into the latter.
