Indeed, people in this thread are way overestimating how many average people even know who Euler is.
It’s OK if mathematicians are obscure in the general population. That’s part of the deal when you become a mathematician. I don’t know many footballers either.
I would much rather the general public filled their heads with basic mathematical concepts, rather than the names of mathematicians. As Feynman said (paraphrasing), knowing the name of something is rather useless if you don’t know anything else about it.
