I read this book but I am confused as to how communism would be implemented in modern times.

How can people get together for large scale projects without a central planning authority or hierarchical structure? Do you just expect workers to somehow arrange themselves according to their abilities to build infrastructure or a supercomputer or hospital equipment? And wouldn't such large scale projects be alienating anyway, since the workers don't see the fruits of their work?

The only answer seems to be that communism would mean reverting back to a simple life...
