For me, solving problems in the kernel is immensely more interesting and rewarding than fixing the n-plus-oneth CSS aligning bug. It also comes with the added advantage of using real development tools instead of nuts and bolts that barely help you.
Apples to oranges. My point is, writing OpenGL code or fixing driver compatibility issues can be just as boring. CSS is not exactly programming anyway.
On tooling, take a look at current webkit/FF/Opera inspectors, TraceGL, TernJS, the upcoming IE11 developer tools and TypeScript. You'll be surprised.
