Yes, but of course, for every system there exist optimums, where any change will either just trade one quality for another, or worsen them all on average.

The best posture for a specific system depends on how far you are from an optimum, and not by mindlessly claiming that "there's not free lunch" or "we can always improve".

Doesn't the fact that a change can worsen all three qualities imply that there must be a change that can also improve all three qualities?

These things are not always mutually exclusive. That's the fallacy.

[marcosdumay]

No, why would you ask that?

Read the full phrase, not just half. I didn't say those are mutually exclusive anyway.

[calinet6]

Gotcha, yes -- it comes from understanding the system and its optimum. Certainly not from mindlessly advocating for either extreme.

I guess everybody gets to put stuff on the Internet before taking a morning cup of coffee, or in a rush. I'm certainly guilty of both.
