> It means we've discovered the actual fundamentals of several areas. But there is some evidence that this is not the case. For example, quantum field theory and general relativity are not quite compatible. [1][2] The mechanism for charge formation in triboelectric effect (when you rub things together) isn't well-understood. [3][4] Turbulence still cannot be analyzed satisfactorily. [5] This last one is even mentioned in the Feynman Lectures [6]. Also, generally, I think we should be very skeptical of the claim that we live at the pinnacle of human achievement and the end of the history. It…

The article's a bit scattered but its central theme seems to be the Problem of Time. There's a wikipedia article on that, of course, and it's not so bad. https://en.wikipedia.org/wiki/Problem_of_time The structure of the the paragraph you quoted and the one following it is similar to the first two long paragraphs under the "Proposed solutions to the problem of time" section of the wikipedia article. There is a bit more here: https://en.wikipedia.org/wiki/Canonical_quantum_gravity#The_... and a technical overview in the first section of https://arxiv.org/abs/1009.2157 I wrote "seems", because…
