Academician Li Guojie: It's possible to start over and rebuild computer technology

CNET Technology Information Network, July 28th, Beijing report (by Liang Qin): Academician of the Chinese Academy of Engineering, Li Guojie, made a startling statement: to date, only about 5% of people own a PC. It is entirely possible to reconsider and design a more reasonable computer to meet the true needs of the masses. "We have every possibility to start over from scratch!"

This afternoon, the Computer Engineering and Application Branch of the Chinese Institute of Electronics held an academic seminar in Beijing. At the seminar, Academician of the Chinese Academy of Engineering and Director of the Institute of Computing Technology at the Chinese Academy of Sciences, Li Guojie, gave an academic report titled "Computer Technology at the Beginning of the 21st Century".

In his report, Li Guojie pointed out that information technology in the 20th century took some wrong turns and paid a heavy price. In the past 100 years, global GDP has increased by 18 times, but energy consumption has increased by over a hundred times. Information technology in the 20th century also suffered from the same issues. For instance, in North America, 10% of energy consumption is used for information technology; 10% of the cost in the U.S. is invested in information technology.

The 21st century cannot afford to make the same mistakes.

Li Guojie stated that the computer industry in the 20th century was distorted, as people spent a lot of money just to keep up with upgrades. Moreover, computer products became increasingly complex. "It seems that in the entire world, only the computer industry makes things more and more complicated."

"In the 20th century, the entire industry pursued and focused on performance and purchase costs, neglecting reliability, usability, security, and other aspects. I feel deeply grieved about this," Li Guojie expressed.
