Answer:
Traditional technologies were initially invented during the time when knowledge were still limited. So, their maximum potential were left undiscovered by the people who live in the past.
The efficiency of traditional technologies can be massively improved by adding some key features of modern inventions.
For example, Wheels has existed since 3,500 B.C. But it only reach its maximum potential in terms of speed, durability, and resistance power only after the latest latex and steel technology was invented .
Other example would be light bulbs. It was created in 1879, but only reach it maximum potential in term of energy efficiency after the invention of LED technology.
