There are (ja dalabym tu przedimek) few people today who could exist without technology. Nevertheless, the invention of 'a' (niepotr) technology also has its drawbacks (ale nie powiedziales, ze ma jakies advantages...).
Firstly technology 'facilitate' (tutaj 'technology' to 3os.l.poj) contact. 'By mobile phone or internet' (ja dałabym to na końcu zdania) we can send text messages and talk with other people. By social networking, we can find friends with whom we had 'not' (zle slowo) contact.
What is more (tutaj musisz dac przecinek, inaczej to brzmi...'more technology') technology improves daily activities. Being at home, we can pay (daj tutaj slowo) bills or buy something we need (można tez dodac 'we want', bo zawsze kupujemy to, co we want').
Thirdly it is (brak przedimka) brilliant way 'of spend' (nie, tu masz zle, albo. 'to spend', albo 'of spending') free time and (daj tutaj 3 slowa, jedno z nich jest przedimek) source of entertainment.
New technologies offer many opportunities (dla kogo? mnie? ciebie? psa? kota?) from 'acces' (ortog) to various online portals 'after by device' (tego nie rozumiem) that can play games.
Moreover (przecinek) modern technology is necessary in medicine and other fields of science. Complex machines 'lets' (niepotr) save people's 'life' (nie, bo 'people' to jest więcej jak jeden, to znaczy 'zycia, nie zycie'). Using 'a' (niepotr) modern technology can warn people about dangers (daj jakiś przykład).
On the other hand technology takes a long time (wytłumacz co znaczy 'long' - 1hr, 10 hrs?).
To get 'all case' (nie rozumiem tego) (kto? co?) often need to spend a few hours.
Even though technology 'facilitate' (technology tutaj to 3os.l.poj) contact with other people it (tutaj brakuje słowa) (musisz napisac kogo) away from reality and real friends.
Taking everything into account technology is 'morst' (ortog) important in 'us' (zle slowo, tutaj OUR) 'live' (tutaj potrzeba rzeczownika) (przecinek przed 'but') but in spite (brak słowa) advantages it also 'have' (ciekawe, ale ja dałabym l. poj) disadvantages.
