This third entry in a series of what can only be called an asteroid belt of topical commentaries wobbles as wildly as its predecessors, careening from artificial intelligence to the joy of libraries to brain chemistry to sex robots to entropy and the origins of life. As usual, the author eschews all traces of continuity and theme in favor of spontaneity, stream of consciousness and whatever sense of wonder can persist in minds five decades old. Sure to annoy, irritate and polarize, this latest volume is an oversized bag of intellectual Halloween candy, with one or two of Charlie Brown's rocks thrown in for good measure.
