It's very interesting that you used the word "perspective" there, and I'd request that you dwell on why I find that interesting, as it relates to my point. You've actually reinforced my point without even realizing it, given that what we have now across the board are firsthand accounts. Think about what a firsthand account actually is.

Put another way, our bar for truth is now understanding. If you misunderstand something I say to you, what you've interpreted is your truth. The world is experienced subjectively and it is very complicated, and misunderstandings happen far too often in my life (in both directions) to not be queasy about firsthand accounts being the new truth.

You feel queasy about firsthand accounts compared to what, exactly? Secondary sources are weaker than primary sources. We now have unfettered access to most primary sources, whereas before we had to rely on secondary sources and their interpretations and biases.

Yes, everyone experiences the world subjectively. How do you inform others of that which is outside your experience? How do you learn without factoring in your own persective? We aren't talking about science here.
