Two bacterias talking, 2 Billion BC

Just read a funny conversation from Ray Kurzweil's book - The Singularity is near. It goes something like this:

Bacteria A: One day, 2 billion years from now, 10 Billions of us will join together to form gigantic bodies capable of amazing things and forming self-awareness. Each bacteria specializing in its own thing to serve this huge body. We won't have to worry so much for food, because the body as a whole will take care of this.
Bacteria B: You're delirious.

Ha, ha,... How true... How could 2 bacterias even imagine that humans will emerge. Now, let's try to make this mental leap once again - what will happen when humans make this next leap??
This idea of a Singularity is totally mind-boggling. Joining the minds of humans with calculation power to a kind of "Gia" that operates as one body... Seeing this happening right in front of our eyes... Truely amazing.

How come I didn't know about Keynesian multiplier before???

Just found out how powerful is Keynesian multiplier in economics... Let's say the government spends a 100$ on foot massages for the Prime Minister. Then the Physical Therapist goes and buys herself a nice meal in a restaurant with 80$ out of them, then the Chef goes and buys himself some nice shoes in the shop with 64$ out of them, and so on and so forth... So... These 100 bucks generated tons of economic activity.

Now, I started to think about green consumerism... I guess the same effect happens here... Environmentally concerned consumers prefer to buy goods from environmentally concerned businesses which in turn buy their services from other green service providers, and so on and so forth... Which generate tons of green business activity towards a green revolution! Now, isn't it empowering to generate so much green economic activity from every buck you spend on green products/services??

Update: Hmmmm... As some of my economist friends have noted, on a second thought, this analysis is much too simplistic. Oh well...
