Blogging about transhumanism I wondered why people, normally so keen on nirvana, heaven etc, are so unimpressed by the idea that we could get closer to that point using technology. Tracy suggests that it's because these high tech solutions seem so distant and unlikely. I think that's a big part of it, it does sound unlikely and kind of crazy (though I also think a lot of people don't like it because the spiritual version just feels so much better).
The thing about the plausibility issue though is, exactly how plausible is it that our consciousness, or soul, survives death? Our minds, along with all our emotions, sense of self etc, are so very dependent on the physical condition of our brains that it seems very unlikely that our consciousness survives death. When someone who suffers from Alzheimer’s disease dies, which consciousness do they get in the afterlife?
Of course that doesn't made the odds that we'll all live a thousand years because of technology, better. Just that we shouldn't laugh at one thing because it's unlikely and then jump on another unlikely bandwagon. In fact I think we should focus our attention where the chances of success are highest, however small they are.
