The whole point of the singularity is that AI could be sentient and even more capable than humans someday; by that logic humans are just a bio mechanical machine on a big scale that’s made to reproduce while not expending too much energy on thinking neurons (which is why human brains are bad at computation, prediction, heuristic analysis, avoiding logical biases etc. etc.). It’s like calling the Great Wall of China “just a building” or calling the Louvre and the history behind it “just a collection of paintings.” You’re missing the big picture and how it effects the culture and world around it, etc.
