A lot of people now don't know how terminals work or even that terminfo exists.

Unfortunately due to the progression of technology and education, a lot of foundational knowledge is not being learned. Terminals are probably one of the biggest losers in this area. Even many technically knowledgeable people only know of terminals as "that box that pops up where you can type commands". They cargo cult/copy-paste the common escape sequences. Most things work "good enough" now that they never have any reason to learn more.
