There are multiple theories on how species evolve. One that has gained a lot of popularity is the idea that huge leaps in evolution (like speciation) occur rapidly and are interspersed by periods of virtually no evolution. What Conan said actually makes sense in this context... Currently we have reached a plateau of evolution in our species. We evolved self awareness through a time period when our ancestors were presented with a time of plentiful food and had the opportunity to basically just "sit and think about stuff" rather than focus on survival. That brought us to where we are today, so the next step would be to have a time when we didn't have to worry about the fate of the planet or each other. In essence, we could all just sit and think again (or do research).
