some say the glass is half full   the glass is half full   the glass is half full   some say that it's half empty   that it's half empty   that it's half empty      oh oh   we should trust machines    to make up our minds   human error keeps us guessing   all our lives   trust the machines   they will keep us   they will keep us alive      some say we came from eden   we came from eden   we came from eden   and some say we all are prime mates   we all are prime mates   we all are prime mates      we should trust machines    to make up our minds   human error keeps us guessing   all our lives   trust the machines   they will keep us   they will keep us alive   alive alive alive         and some say the end is coming   the end is coming   the end is coming   some say that we're just starting   that we're just starting      yeah   we should trust machines    to make up our minds   human error keeps us guessing   all our lives   trust the machines   they will keep us   they will keep us alive   alive alive alive alive ...
