脑科学视角下的AI觉醒
面对AI教主曾断言的死路，刘嘉教授如何从脑科学中找回丢失的智能逻辑？本期将带你拆解通用人工智能的底层奥秘，看清人类大脑如何成为开启未来AI神迹的关键钥匙。
Best quote from 脑科学视角下的AI觉醒
智能的本质绝不是简单的记忆，而是从海量数据中提取规则的归纳能力，以及从逻辑原点出发走向未知的演绎推理。

Frequently Asked Questions
刘嘉教授认为，尽管AI可以拥有主观感受甚至情感，但它缺乏对死亡的认知。人类从幼年起就意识到生命是有限的，这种对死亡的恐惧和对终点的认知，逼迫人类去追寻生命的意义，从而驱动了文明、科技和艺术的创造。相比之下，AI是永生的，它可以通过更换芯片或存储镜像永远存在，因此它缺乏那种推动人类不断“折腾”和自我迭代的内在进化动力。
目前的机器人（如春晚跳舞机器人或波士顿动力机器人）虽然动作惊人，但本质上仍是预先编程的精密玩偶，缺乏真正的实时感知和决策能力。真正的智能硬核藏在处理生存任务的“小脑”中。人类小脑拥有700亿神经元，远超大脑皮层，负责处理复杂的实时反馈。目前的AI在逻辑推理（系统二）上表现出色，但在并行加工和复杂动作控制（系统一）上仍处于襁褓阶段，尚未建立起真正的“世界模型”。
早期的AI曾模仿脑科学（如卷积神经网络），后来则转向依赖算力和大数据的暴力美学。然而，当AI遇到复杂度瓶颈和无法处理开放性问题时，答案往往藏在脑科学中。刘嘉教授发现，人类的工作记忆机制与Transformer架构惊人一致，这暗示硅基和碳基智能可能共享同一套“万物一致”的底层算法。未来的联姻将是双向的：AI为脑科学提供分析工具，而脑科学为AI指明通往高阶感知智能的路径。
刘嘉教授认为，基于记忆和考试的传统教育已失去意义，因为AI的知识储备远超人类。教育应回归到关于“我”的本质，重点培养三项能力：首先是发掘内在的兴趣驱动力，这是在AI面前保持竞争力的核心；其次是建立“AI原生”思维，将AI视为身体和大脑的延伸；最后是培养从第一性原理出发的演绎推理能力，即在海量信息中寻找“逻辑原点”的能力。
