Thanks for the comment, it seems today is the "philosophy" day on Steemit. I got in another very nice discussion on @dantheman post about consensus.
First of all, it's not criticism, it's opinion. It's my way of seeing things. As for inference on top of other inferences, things are way subtler. What I was referring to was our ability to create reality from suppositions.
For a long time, we thought the Earth is flat.
And then we realized it's round.
And then we thought Sun is rotating around Earth.
And then we realized Earth is rotating around the Sun.
There is no intrinsic way to know when our inferences will be proven wrong again. We simply don't know if our model of the universe right now, this one based on atoms, is actually true. It passes some tests and it fills in some gaps, but that doesn't make it automatically true. For centuries, people were absolutely convinced the Sun rotates around the Earth, because it passed some tests and it filled in some gaps.
Our current way of understanding the Universe, based on science, seems very fragile to me, that's all.
