I still use dial up, but only for FidoNet.
It's not really a viable option these days...most webpages are bigger than most videos we used to download in the olden days. Twenty million random bits of javascript are included on every page, just for fun, and there's another dozen included because they're actually needed. Then everyone has a photographic background these days of a high res image which can - sometimes literally - take an hour to download over dialup.
Your high speed internet is probably faster than you think it is, it just doesn't feel like it because the internet turned into a bloaty piece of crap over the last fifteen years. You will notice it when you go back.
