I have a hard time with this mentality. I would have agreed a few years ago perhaps, and do still agree that we all have our own aptitudes, but the level of absolution in a statement like this just isn’t really quite as applicable to humans in my opinion. There are things I never thought I’d be capable of that I’ve recently begun to excel at.
What I thought was a hardware limit turned out to just bug in my psycho-software that needed a patch. Obviously at the extreme end’s of the spectrum, the human hardware limit is very real. But for most (healthy) people, engaging in most activities, I believe that any perceived immutable barriers or obstacles are almost entirely psychological.
