An interesting counter-example is an ecosystem - more components and interactions equal more robustness.

What's so robust about an "eco-system"? What functional elements of the "eco-system" are you claiming this robustness for?

If I've very carefully selectively bred, say, an ant colony to create tunnels in patterns that represent the solution set for a given computation, I've got a very fragile system, not a very robust one. I'd need massive amounts of parallelism to match the correctness of even a small microcomputer, in order to statistically correct for all the flaws in the individual ants.

Ecosystems are only robust in that it's reasonably hard to competely disrupt all biological processes in a given area, due to sheer numbers. But then again, it's even harder to destroy all geological processes, let alone radiation processes, due to an even bigger problem of scale.

And even when we examine ecosystems, we find that the small,simple organisms: like, bacteria, grass, and insects often tend to outlast the big, complicated ones (dodos, dinosaurs, and sabre tooth tigers).

K.I.S.S. is a good principle.

[Corion]: Hmmm. I feel a Meditation coming on. I wrote a module, DBIx::PivotQuery, which returns a table-like set of rows (AoA) but some columns are generated from column values, like in an (Excel) pivot table or a ROLLUP command
[Corion]: My current approach for subtotals involves rerunning the given query, with the hint to the user that they should use a temporary table if they want better performance.
[Corion]: But I could create that temporary table in the module and use it for the improved perfomance directly instead.
[Corion]: And the question is, what would be better/preferred ;-)
