Receiving and trusting information is essential to being human. We don't have to prove everything to ourselves from sensory evidence and first principles because other people can credibly tell us things.
We have to verify via prior sensory experience (past experience) if the person speaking in the present is credible. How do we do that with limited sensory experience of their character? Personal ignorances and biases due to lack of experience?
We have to understand how to leverage the first principles of math to extend them, and teach those to others to propagate the knowledge.
Not really sure it’s possible to remove sensory experience from … well any understanding of the world.
Not sure what you wrote makes any sense.
To have no ability to determine whether a video, or image (or any media) is from a reliable source forever more, seems like a pretty bad place to be in - if this is what you're suggesting?
