Many of my teachers, most even, could have been replaced, with with some gain, by high-quality videos and quizzes.
The point is between a simulacrum of a dog, and an actual living breathing dog with its own wants/needs/spontaneous behavior and personality.
Similarly, the expectations of an actual teacher, vs just self learning with tests.
This issue is captured in Blooms 2 sigma problem.
Someone get's hives around dogs. Perhaps the online version is better.
Depends on the need.
I want to learn about all dogs. Online would offer more. I want to learn more about this one dog perhaps locally observing is better.
Depends on the technology at the time.
Online might offer the same experiences locally in the future. VR might give you the chance to meet that dog and interact virtually.
