I fundamentally disagree on both points. I'm of the belief that understanding is only ever "less wrong", and can only be asymptotic to "total knowledge". Thus current "understand most" is really (and ever going to be) "understand very very little" - there's always infinitely more to be less wrong about; Also as an example: electricity - our brains wouldn't work without it, yet it took us very long to understand the principles enough to be able to do anything useful with electricity; What about consciousness - we can't even seem to agree on a single definition much less "understand it" - perhaps we're still missing something as "big" and as much "part of us" as electricity? This is not about being smarter as it is about fundamentally different orders of magnitude of complexity. Getting a whole swimming pool full of tapeworms will not make them any more human - and in the same sense a whole planet of humans won't make them any closer to more complex beings (whatever they may be). As I said, this solution is uninteresting because by definition bacteria/tapeworms/humans can't comprehend "up". And yes, evolution, understanding of the universe and technology may as well bring us to the point when _they_ understand - but by that point, to us now, _they_ won't be human (`bacteria < tapeworms < humans now < next_order_beings`).
