I remember Obama said something along the line to tech leaders, "Your job is a lot easier when you only have selected group of customers to please, but when you have to cater for everybody and every interest group, things are a lot harder." Paper based document will continue to be used for a decade or two more.
Why cant we just have both? Too much man power in auditing or publishing? Well that is what tech is for, automate it. The tech should be catering for its users, which is not just the public but civil servants as well ( I cant believe I just wrote that ), not trying to force the tech on everyone else.
P.S - I thought PDF/A is an open standard. Why is everyone suggesting PDF is a closed format?
