You lost me in the last sentence. I think what you said rings true with an exception. I don’t believe that the people you’re referencing will bother with learning how to care again. It would be a tacit admission that it was willful ignorance.

This one has been easy for me lately: They spell ‘lose’ as ‘loose’.

Good points, 12 seems to be superior and I’ve changed my opinion.

I’m not experienced with RPN but at a glance think there’s a solid argument for it.

Base 16 is superior and once you learn binary math, easier to divide and multiply.
