What do you think about teching with technology?

In my opinion, technology is a necessity in the classroom. For example, illustrations and video links help in demonstrating key concepts to the students which can't be explained without the use of some diagram or abstract via technology. For example, as a science teacher, I think key concepts like the sharing of valence electrons are better taught through video links.

Animated  diagrams are also technologically advanced tools that help recreate abstract simulations of science. Hence, in your opinion do you think just lecturing would be more beneficial in the classroom or lecturing with the aid of video technology and animated pictures? Moreover, YouTube sites are banned from being accessed in school. Should this type of ban be placed for teachers also?
