How would uncivilized cultures react upon receiving technology beyond their comprehension?

I’m not sure if everyone in a single culture would be able to receive technology. First of all, this question states “receiving technology beyond their comprehension.” Beyond their comprehension already confirms that not all people will be able to grasp that kind of knowledge.
Psychosocially, older people have a harder time comprehending new, abstract ideas. The reason for this is because as people grow older our fluid intelligence, the ability to think and solve abstract problems, declines. This doesn’t mean our brain turn into vegetables as we grow old because our crystallized Intelligence, the knowledge gained from experience, is still in tact. With this knowledge, I assume that the elderly in the uncivilized culture will have a harder time comprehending new technology. We see this happening even in our own “civilized” society. If someone said “My grandma has a cell phone and occasionally texts me,” most people would respond, “Wow! Your grandma is awesome!” This shows our prejudice against old people.
With everything said above, I’m still uncertain of the answer to the question. Looking at Korea’s past, we’ve overcome from being at the bottom of the economic class to the top within about sixty years. Even in the late 1800’s to early 1900’s Korea may have been considered as an “uncivilized” culture. However, I would consider Korea’s state to have worsened during World War II. Coming out of annexation, Korea was socially worn out and seemed like we wouldn’t be able to stand back up even if a century went by. Surprisingly, Korea responded conversely and has become a powerful country. Different cultures have their own way of receiving technology; therefore, answering this question is quite difficult.
