Why Our Brains Will Never Live in the Matrix

When surveying the goals of transhumanists, I found it striking how heavily many of them favor conventional engineering. This seems inefficient and inelegant, since such engineering reproduces slowly, clumsily and imperfectly, what biological systems have fine-tuned for eons, from nanobots (enzymes and miRNAs) to virtual reality (lucid dreaming).

Recently, I was reading an article about memory chips. (See Resources) In it, the primary researcher makes two statements that fall in the “not even wrong” category: “Brain cells are nothing but leaky bags of salt solution,” and “I don’t need a grand theory of the mind to fix what is essentially a signal-processing problem.”

And it came to me in a flash that many transhumanists are uncomfortable with biology and would rather bypass it altogether for two reasons, each exemplified by these sentences. The first is that biological systems are squishy — they exude blood, sweat and tears, which are deemed proper only for women and weaklings. The second is that, unlike silicon systems, biological software is inseparable from hardware. And therein lies the major stumbling block to personal immortality.
