In-person viva and maker-based assessments for ed-tech in the AI era

If you are an ed tech company, steal this idea: In the age of AI, the only way to "properly" do assessments is by either taking pen-and-paper exams, or via personalized, in-person vivas, which could require students to "make" things (e.g. circuits, demos etc) beforehand and explain them offline. Any technology or tool that makes such assessments easier to do and at a large scale stands to be extremely successful. Think Gradescope, but better and more scalable.
