"System change is now inevitable. Either because we do something about it, or because we will be hit by climate change. '...

"We need to develop economic models that are fit for purpose. The current economic frameworks, the ones that dominate our governments, these frameworks... the current economic frameworks, the neoclassical, the market frameworks, can deal with small changes. It can tell you the difference, if a sock company puts up the price of socks, what the demand for socks will be. It cannot tell you about the sorts of system level changes we are talking about here. We would not use an understanding of laminar flow in fluid dynamics to understand turbulent flow. So why is it we are using marginal economics, small incremental change economics, to understand system level changes?"

Neither Duck nor Non-Duck

Yet again, the truth, as it so often does, lies midway between the extremes.

By the way, if anyone understands the immediately preceding xkcd strip, I'd appreciate an explanation. Call me thick but I really don't see the point.

Looks like the brillaint design with umbrella doesn't work - they get wet.

My explanation of strip 689 would be that the cartoonist has some off days.

Much earlier, the guy with the hat saw through, George Nada-style, the whole 9-11 hoax, and revealed that the towers are still standing.

The umbrella strip: you have to be familiar with the various competitions at MIT and other places where the competitors build robots in order to do things like put balls into holding containers. Often there's a balance between designing a robot that is really good at ball pushing, and designing a robot that are really good at messing up the other robot (and, of course, designing robots that are robust to the other robot).

So, this particular robot was designed to set off the sprinkler system in other to kill its competition, but the umbrella keeps it dry enabling it to still get points by pushing balls around.

Does that help? I never took any of the robot design classes, but had enough friends who did that I still found the strip funny...

marcus, makes perfect sense, thanks!
