Most people have their idols, be it scientists or pop singers. Many youngsters, in particular, worship stars in the sports and entertainment field, who catch most of the public attention.
It is hard to say whether idol worshipping is good or bad, for it is not a black-and-white issue. For one thing, these public figures walk into the spotlight after a great amount of hard work, therefore they set up role models as talented and industrious persons. But for another thing, it may not be wise to blindly admire anyone. This is dangerous, because to err is human and stars have their weaknesses as well, and in some cases, even scandals.
As I perceive this phenomenon, there is nothing wrong with idol worshipping inherently. What matter are the aspects in which we admire them and to what extent it goes. Even if a certain star always presents a good public image, the "worship" should not go to such extreme as pure imitation, otherwise there will be a lot of "carbon copies" lacking individuality.
