中国工程院院士、清华大学计算机系教授李三立认为，光子、量子、分子和生物计算机以及神经网络计算机不会成为我国计算机的主流，个人计算机（PC）仍将在一个长时期“唱主角”。国际上也普遍认为：2000年以后是利用因特网为管道，计算机等信息产品大量进入家庭的“后PC”时代? Li Sanli, a member of the Chinese Academy of Engineering and a professor of computer science at Tsinghua University, believes that photonics, quantum, molecular and biological computers and neural network computers will not become the mainstream of computers in our country. The personal computer (PC) will still “play a leading role” for a long time. Internationally, it is generally believed that after 2000, it is the era of “post-PC” that a large number of information products such as pipes and computers are used to enter the home by using the Internet.
