Can we live without Modern technologies?

My opinion is yes we can live without modern technologies as our ancestors did. Living without modern technologies would be life with out colours for us. Sometimes I compare my livings in UK with third world country village where there is no electricity, Gas, transport system. I can not live without electricity as I have to use computer and using computer without Internet is like i am in a room having TV but not transmission. When I use Internet I feel whole world is on my finger tips. I can find my acquired information easily. My whole entertainment is on Internet. I do not watch TV, I use my computer as TV whether its bad or good but I do. What do you feel? Can you live without modern technologies in a third world country?
