This is very true. The problem build tools are solving is complex.
When designing a build tool you can choose between simple and powerful.
Qbs chose the latter.
However, one can design a powerful build tool with a front-end language
that doesn't make you want to scratch your eyes out.

I wouldn't know where qbs gets "confused".
Don't spread false information and let it die in peace, thanks.
On the topic of why build tools ignite such hot discussions I have my
own theory: Experience shows that Jane Developer sees the build tool as
necessary evil. She doesn't give a damn about details and grudgingly
invests time in learning as much as is needed for the task at hand. Over
time she gets a specialist - unwillingly - and defends this investment
made with teeth and claws.
