Thank you very much for the explanation. I think I get the point but remain skeptical. Is knowledge (even a totally man-made subdomain like OS&#x2F;App) fundamentally scattered in nature, or can be modelled in the scale of 0.1% of the original size?<p>It&#x27;s kind of odd that Alan Kay, the visionary of DynaBook, who advocates the importance of exchanging of ideas, has the belief that a single man should be able to handle thing of the scale of industry. Karl Max believes in social labour division, and I think he is right.
