For me, I find it unsettling because it's a reminder of how ultimately we're all just compositions of atoms with electric signals in our body. While I find this immensely exciting, it unnervingly reminds me of my mortality. It's akin to what I imagine Neo would've felt when he learnt about the Matrix. I'd like to think I'd have without a doubt taken the red pill too (like I want this kind of research to be more successful) but anything that makes the Matrix more real is unsettling.
