The most important invention of all times

Many important inventions were invented in the 20th century, cars, computers and more.
Today, all the Inventions are so important beacuse we use them everyday. These inventions changed our lives and made it(gr. - them) easier. Some people think that these inventions destroying(gr.) the world

I think the cellphone (is) the most important thing in everyday(life) beacuse(sp.) it saves(ww. - prevents) worry and problems. Anyone who has a cellphone take(gr.) it with him to(מיותר) everywhere. The cellphone makes the life easier and your perents(sp.) didn't(gr.) need to worry about you when you go out or when you are late. For example, when I go to the movies with my friends my pareave to worry(what?), I can talk to them all the time.

I asked my perents and my grandperents which (was the) most important invention for them. My mother said that the most important invention is the cellphone, beacuse she's all the time on the cellphone/phone(wo.), and she's(מיותר) likes the cellphone, she also works in a job that requires (a) cell phone. My father said that the most important invention is the car, he's(מיותר) likes the car and always loved to drive his car, (he) hates bus(es)  and taxi(s). He could(gr. - can) go anywhere he wants.

My grandperents said that the T.V is the most important invention beacuse they likes(gr.) to heard(gr.) and to seen(gr.+ww. - watch) news. In addition, it updates them(מיותר) (on) all events in the world and They updated everything(phr.). They can't (do) without the T.V, It takes the boring.(phr.)

I think there are differentces between the opinions about the most important inventions is the most (מיותר) beacuse (of) the difference in age(מיותר) ages. My grandperents think that the T.V is so important because they  barely use the cellphones. Currently, these inventions do not matter to them, they do not need it so they need only the T.V.
