is my English 101 thesis good enough? "Technologically mediated interactions have impacted the way people socially interact both positively and negatively"
Overall, yes, but I have some suggestions for you to make it readable by regular, everyday people.
"impacted" literally means to hit or strike
I think using the word "affected" or "influenced" would be better.
Now — take the first three words and let us know what that means in normal English!
