In the Fermi paradox, philosophers and scientists wonder why we are not receiving any radio signals from alien civilizations. There are many billions of planets in our Galaxy alone and there should be many civilisations.
Well, I have a theory. I think that less the 250 years after discovering radio, the civilisation is destroyed by its technology and this happens throughout the universe.
Here on Earth we missed a few nuclear winters thanks to patient commanders that dismissed faulty sensors during the cold war and there are many nations that are developing nuclear weapons.
The problem we are facing now is people's jobs are being replaced by machines. You see machines don't pay income tax, they don't buy things and they don't pay any bills. They don't want anything. Capitalism relies on consumers so when the teacher is replaced by a hologram,
The policeman by a robot,
The GP doctor by a universal diagnosis machine, the bank clerk by an app and there are no jobs left then our society will fall apart because there is no tax revenue and no business and no trade.
The way to stop this is to refuse to be served by a machine. We must ensure that a human serves us and give bad feedback to any company that forces us to be served by machine.
Then we will get machines to improve themselves and they will make themselves more intelligent than us. That is another story.
