The steam engine revolution provided humanity with endless power to manufacture
The railway revolution brought humans closer together, the geographical circuit board became denser, moving from 20nm to 5nm
The electrical revolution liberated people from tedious labor, allowing for production, which also unleashed productivity.
The internet revolution further enhanced human communication, leading to larger clusters of human production.
What will the next revolution be?
Perhaps it will truly be robots/unmanned devices, once again liberating human time.
But the time is not yet ripe, why?
The truly labor-short American manufacturing industry is no longer present, while China has not yet reached the point of real labor shortages.
Maybe it will still take 20 years.
