Sorry, that's absurd. When you're talking about making everything yourself, there is no way 2,000 people could design and construct computers from scratch, and write all the necessary software. Or anything they did produce would be decades behind today's computing, due to only a fraction of the people working on it.
Not to mention that only a small minority of that 2,000 would be available. Even if you dedicate 10% of your resources to it, that's 200. That's the sort of scale for one or two single software products, nevermind trying to reinvent an entire computer industry!!
What does "living with the enviroment, not against it" mean, and how will it mean we can produce food as efficiently as we can now? I want answers, not assertions like "Everything will be much better because I say so".
