Teaching complex, abstract content is the key foundation of our civilization. Even before Internet there were technologies which thus significantly improved teaching and learning process and accelerated development of human society. With Internet and digital technology a number of new, powerful technologies are available to education. They significantly change the role of the teacher. No teacher can provide data, information, explanation, discussion or advice that cannot be found online nor can do it better than someone already did, or will do online. However, instead trying to do all for all, modern teacher should focus on doing something particular what they excel in for a fraction of students who truly need that teacher. Due to Internet the quantity of that small fraction of students will be larger than ever. Schools also need to transform, both physically and institutionally. Physically they need to provide spaces and resources for collaboration and exploration as well as cohabitation with their teachers. Institutionally they will specialize for some aspect of educational process from creation of new knowledge, its curation to its assessment.
