Multitasking Agreed. But you're providing reasons why we shouldn't change it. And, as you pointed out, scientifically, we don't have the means or the knowledge to change it, even if we could.
But that may not be the case in the
future. If we look forward ten thousand years, it's entirely possible neuroscientists then will have the means to remodel consciousness on an anatomical level.
When that happens, to what extent will any of the "eternal" philosophies of today survive?
EDIT: People like to think their questions are "eternal." We will "always" search for meaning. We will "always" have concepts of God, or zero. Is that accurate? Thoughts are physical processes. If the underlying physics and anatomy behind the brain changes, the very nature of thought will change, too. I can easily imagine a future where many of the "eternal" concepts people argue about today will simply be incomprehensible to our descendants.
EDIT: Also, more specifically, what are the mechanical limitations of human thought? I've mentioned one. What are the others?
