I don't think it would be that profound though. If we had extra time, it would just seem to pass by faster.
Like we live many times longer than cats and dogs now, and we have a higher level of consciousness than them. But is it really a blessing or a curse? We just see the cat and dogs territorial fights as really trivial while we worry about bigger things like Trump presidency and climate change. Sometimes we even envy the cat who lives happily as a pet.
Even if we became more significant, like 1000000 year old planet eaters, it would just make everyone else relatively trivial and we'd still have to worry about bigger things.
