how to understand modernization properly I mean rav Kook etc? how to understand it from point of view of tradition and Torah

For anyone who believes in God, just like it's illogical not to recognize His Hand in fulfilling the prophecies of the ingathering of the exiles, so too we can't ignore His wondrous opening our eyes to reveal the miracles of modern science and computers etc, which He meant for us to use properly and surely not to neglect or shun. Anyone who stubbornly refuses to see this as God running the world, obviously has a lack of emunah (belief). All of life is challenges, to choose right and not wrong, and this is the case regarding, for example, nuclear physics, which should be used to heal cancer and not make nuclear bombs (unless they're necessary for our self-defense and deterring the evil). Computers are meant to significantly raise Torah learning in quality and quantity, and obviously not for negative things. The Zohar teaches that as we approach redemption, God will "open the gates of wisdom", which refers to advances in Torah, but also to the secular world, which God obviously also runs!
