I'd say both.

Is it really within the reach of most people to be able to whip up figures like that in a few minutes?

I'd say no.

This is a question that goes directly to the core of my competence. In general we're living in a pioneers' era where demand trumps offer overwhelmingly.

The tools we have, we don't use them because they're the best possible tools, but because they're the only tools available.

We are in such a need of any tool that works somehow, that we're deceived to think that they're wonderful when they're just slightly better than the rest. The space for improvement is vast, including a tool that would make those diagrams easy for you.
