This argument in this industry is problematic. The entire purpose of computers is to automate processes that are labor intensive. Along the way, the automation process went from doing what was literally impossible with human labor to capturing ever deeper levels of skill of the practitioners. Contrast early computer graphics, which involved intensive human intervention, to modern tools. Since HN almost certainly has more developers than graphics artists, contrast early computer programming (where programmers didn't even have the assistance of assemblers and where they needed a deep knowledge of the computer architecture) to modern computer programming (high level languages, with libraries abstracting away most of the algorithmic complexity).

I don't know what the future of indie development looks like. In a way, indie development that uses third-party tools that captures the skills of developers and graphics artists traditionally found in major studios doesn't feel very indie. On the other hand, they are already doing that through the use of game engines and graphics design/modelling software. But I do know that a segment of the industry that utterly ignores those tools will be quickly left behind.
