Yes and no. I do agree that probably nobody's going to build another Eiffel tower or Crystal Palace any time soon,but we need spaces to explore science, innovation,and simply have for people to do something more interesting than just mindlessly walking through shopping malls. Fairs and expos inspire. I still remember going to a tech expo as a teenager and seeing all these latest gadgets and thinking: I want to be part of it! Now imagine going to one of these in the middle of last century and seeing rockets, nuclear car prototypes and things like that. You almost instantly want to sign up or at least show it to your kids.
