I like to think that I have "hardware acceleration" for typing on QWERTY keyboards because I am so used to it that I do it unconsciously.

But when I smoke weed, I have to actively think about the position of keys in the keyboard in order to type coherent things. I have to type "by software".

The point is: maybe for some people, their spoken language is "hardware accelerated" and for others, thinking in words is too computationally expensive, so they resort to less expensive methods.

Or maybe it's the opposite. Thinking abstractly is the computationally expensive method but the improvement in decision making isn't worth the effort.

Disclaimer: I know absolutely nothing about psychology or neuroscience. I just like to think about it.
