Some people also argue that the pen and paper method, by not being instant, drive some extra engagement in the political process, so could be seen as another positive rather than a downside — coverage of vote counting can go on for hours (or days) and it's the one time that democracy is visibly "exciting". This feels like it has a ring of truth to it, but then personally I'm interested in politics so maybe that's a self selection bias — would be interesting if there was a formal study on this.
