Of course they will. You won't get an argument from me on that point. The landlords better be ready, though, for a lot of claims when "little Johnny" walks into a pillar because he's not watching where he's going! As for the "time moves on" point; is that always a good thing? As a fully paid up member of the FOC club, I'm not convinced that it is universally a good thing.
I's not, you're right. Many fantastic old buildings have been demolished to make way for dreadful modern buildings(at the time). The Arndale Centre being the worst building in my opinion, that will forever blight Manchester city centre.
