"hard" doesn't refer to the difficulty level of "hard sciences", but the solidity of the evidence. Basically the same as "hard" evidence in a court case (video footage of a murder, procured from a trusted source, with witnesses and murder weapon intact, as opposed to mere circumstancial evidence).

I know they don’t and didn’t say they did. However, there are implications (if you’ve ever worked with physicists or even engineers you’ll feel the results of these implications), so I suggested that if you do look at it from a different perspective, then you get what I said.

I just don’t think they’re useful terms. In many ways, physics and chemistry are the low hanging fruit of science.
