When will China start innovating instead of copying?
When will China start innovating instead of copying?
The truth is, China is already the most advanced country in the world and if we ever manage to modernize our infrastructure and manufacturing, we will be copying them.
Trust me I would love for China and India to start innovating and advancing the human race but taking the idea of a train and making it faster is just an iteration on a previous technology.
