What do you think of young people's growing distrust of their ancestors?

With the development and progress of society, many things are progressing. Especially now, young people's ideas are constantly changing, and the speed is very fast. They are increasingly distrustful of what our ancestors left behind, because they think that their ancestors' things have long been out of date. Now is the information age, an era in which technology and knowledge are king. It is normal to distrust what one's ancestors have. Indeed, many concepts have long been out of tune with the present era. I can't trust everything about my ancestors. I should take the essence and discard the dross.
