`  == The fifth generation computer systems project? ==  Can you call Japan's fifth generation computer systems project once a promising candidate of ``disruptive technology``? The fifth generation computer was not of ``lower performance or less expensive``. These computers were expected to be more advanced (VLSI, ULSI, artificial intelligence, expert system, ...) than other computers of its days in hardware and software. They planned to create a HAL-like computer that understands and answers your questions. In my opinion, internet was the disruptive technology. Rather than making each computer a silicon Alber Einstein, countless dumb computers are connected and each of them has a human brain or database attached to it. Your computer still knows nothing, but some people behind their equally dumb compuers may have your answer.   `
