Here's an example of a narrative paragraph according to my travel experience.
I had the most memorable travel experience last year. My family and I visited Japan for the first time. We stayed in a robot hotel called "Henn na Hotel." This hotel looked out of this world with many robot staff attending to our needs. In Japanese, "Henn na" means "strange"–thus, the name of the hotel. Our room could only be accessed through facial recognition and it was fully-equipped with modern amenities. It was a fun experience! Later did I find out that the robots in the hotel were not actually functioning on their own, but were being directed by some hotel staff behind.

You would use a comma. The semi colon acts when both what is in front and behind it can stand alone as a sentence. “With technology in the hands of so many people” does not make sense standing alone.
