I agree that it's a lower standard. I didn't mean to endorse Wei's claims in the original post, certainly not based on nanotech alone. If you don't personally think it's worth more of your time to pay attention to nanotech, I'm sure you're right, but it still seems like a collective failure of attention that we haven't talked about it at all. You'd expect some people to have a pre-existing interest. If you ever think it's worth it to further describe the conclusions of those 50-300 hours, I'd certainly be curious.
