#人类的科技, whether it is close to the limit #

In fact, human beings have not opened a new technology tree for almost 100 years!

Now human energy utilization is still very simple and rough, energy into power basically by boiling water, human beings have not been out of the solar system, even their own body and the earth itself has not been clear, the movement of the fluid can not be calculated, the treatment of colds rely on virus self-limitation, the most powerful weapon is only physical explosion, battery efficiency and its low, many top scientific research purely by luck ...

Many of the cutting-edge theories have not been proven or commercialized, such as the quantum field, or controlled nuclear fusion.

The point is that the situation is still relatively urgent. If nuclear energy is not dealt with before fossil energy is exhausted (solar energy is also nuclear energy, there is nothing wrong with it), it is not just a matter of civilization regression, but it is locked up. You don't have the energy to open a large research, the mine is gone, what kind of rioters to take? Because we are unable to organize larger-scale industrialization, we cannot further test our scientific theories, and scientists are blindly guessing that they are much more ferocious than the folk science.

More urgently, if we don't escape the earth before the sun becomes a red giant, we will be eaten by the sun and humans will collectively pounce on the streets. Of course we have 5 billion years of time, and this problem is farther away than the previous ones.

So, always have a goal, it's never enough.
