通过材料质别来批评计算机不可能产生意识,借用 Wiener 的话,不禁让人感觉是活力论者的空虚的辩护,类似当年的有机-无机之辩。
题外的一点想法,如果肯定计算可以产生意识,从材料与计算的关系出发,等于说材质的介质影响了计算模型的性质。这似乎并不是完全不可能。这一方面的问题不知道有多深刻的研究。之前扫豆瓣的时候粗浅的感觉,似乎这本 Classical and Quantum Computation 会有一些想法?不知道计算理论那边会怎么叙述这一问题。毕竟计算模型及其能力能不能进行量化的比较,它们会不会构成一个连续统这一类的问题,已经超出我的能力之外了。等有时间应该回头反思一下。
Dreyfus的想法:只有大小和回路结构近乎完全相等的联结论系统才能模拟大脑。 - Is that real? Why? 如果成立的话,那么计算模型与计算模型间的差异将成为一个更加重要的问题。为什么是这个结果?

Lecture 2 Person Re-Identification (2020.10.10) ?

It was one of the most hopeless period when I hiked to Nanhui twice. I failed to pass almost all the mocks in September, 2018. There were countless assignments and tests to be finished, crowded tutorial classes to be taken, and endless scoldings to be suffered from. National Day in 2018 thus was destined to be a hard one.
However, I was fortunately gifted with several short breaks at that time, one of which was spent in Pudong Airport.
Though located at the seaside, uninhabited and remote, Pudong Airport is among the largest airport in China Mainland. Highways are thronged with vehicles. Green Carriages of Metro Line 2 and the famous Maglevs in Shanghai occasionally rush past.
I have sincere affection for Pudong Airport. My 'first love' left for America for a short-term exchange program years ago. I couldn't see her off personally in Pudong Airport. Later in my senior school, I daydreamed for a long time that I can jump into a plane and escape from myself in the airport.
Night had felt. The giant-like streetlights had been lit. Its dazzling light went through the mist, adding illusion to the scene. Night in October in Shanghai shouldn't have been that cold. Trembling, I left the metro station, and arriving at the huge airport.
People were busy catching their own flights. I ordered a cup of coffee and sat there, watching the passengers. It was in a sudden that loneliness rose in my heart. I had nothing to chase, but daily routine to follow. I arrived at the airport, only to find that there was no proper flight for me. Maybe my situation was much worsen than Nora Helmer.
