I have not come across such a strong ignorance, basically, if you ask people about cryptocurrency, they will answer that they only know Bitcoin. Nobody really knows about altcoins. But I'm sure this will change soon, possibly as early as 2021.
It is not certain that the mindset will change in 2021, as long as there is no education from the community or seminars that discuss cryptocurrency that achievement will never come. If that's all there is I think it will be faster to adapt to learn about bitcoin and altcoins.
