While CS theorists pursue the beauty and unity of their mathematical theories, their results can have a practical and industrial impact.
As we know, P versus NP is often talked about with its relation to public crypto. systems. Moreover, streaming algorithms often directly lead to industrial benefits.
Is there any possible research direction that would satisfy the following conditions?
(1)Solving problems in this area of TCS would lead to a fundamental change in our society.
(2)It would be required to understand other academic subjects (such as physics or electronics) to solve problems related to this TCS field.
I am afraid that this question is not appropriate for this stack exchange, but please forgive me if it is.
