> Why wouldn't it be a huge mycelium? Why hadn't it? I mean, not only doesn't it posses a drop of intelligence, there isn't even something similar that does. And that's after billions of years. My guess is something like this - intelligence is the most powerful evolutionary weapon and due to the way evolution works, you only get that weapon if you have to survive among powerful adversaries. However, intelligence is of no use if the species can't react fast enough according to changing circumstances. Something with mycelium's structure can't run, can't hide and can't attack fast enough. If it somehow evolves to the point it could, it would start resembling existing intelligent species. > More so it's entirely unclear why the life should have to be intelligent - or intelligent in a individual-animate-tool-building-animal kind of way. All life doesn't have to be intelligent and it's not, even here on Earth. It's just that here we are discussing intelligent life that can build stuff. > I'm very unconvinced that even Human civilization or life (should it survive for another 10,000 let alone 100,000 or a million) years will resemble anything like the organic individuals Come on, we've had millions of years of evolution and we're still monkeys with less hair. Unless we start meddling with our DNA and/or actually develop artificial intelligence, we won't be changing much.
