Weinberger is cited here thusly: "But now the medium of our daily experiences — the internet — has the capacity, the connections, and the engine needed to express the richly chaotic nature of the world."

Capacity, perhaps. Connections - to what? For whom, when? Engine, not a chance. The 'engines' we build are all about monetizing the internet. Which will never "express the richly chaotic" anything. There are no other 'engines' of significance, because they won't return a profit in a profit-addicted culture.

The internet is a reflection of our existing society and what we do with tools we create. Long ago (in internet time) there was a dream that the internet might do what Weinberger suggests. But realizing that dream would require a very different culture at the controls.
