What a difference eight years makes in the pc world. Today many pc owners have 1,000 times that total memory capacity. And digital video cameras with full color capability operate from the pc's for extended periods of time. But remember the issue is human equivalence and we discover that the human brain doesn't store much sensory memory at all. Thus the machine far surpasses human equivalence by this criterion.
Mass storage gives intelligent machinery a capability far beyond human sensory memory.
Discs and tapes are quite inexpensive. A human security guard for example will be able to provide very few details of the last shift using sensory memory. Thus by these standards the machinery far surpasses human equivalence. It can also use sensors such as distance-thermal detectors and radiation detectors which humans do not have. The sensory capabilities of machines go far beyond those of humans by many criteria.
