The web is not a tangible place but its spaces still present obstacles to some, and the US law designed to ensure equal access to all—the Americans with Disabilities Act (ADA)—didn't contemplate the abstractions of postmodern life when it was passed in 1990.
Now, Domino's Pizza is asking the US Supreme Court to review a case about the ADA (pdf), which guarantees equal access to public accommodations, and how precisely it applies to the internet and apps, if at all.
The question seems almost quaint at first glance. While the ADA was written with physical places in mind, the realness of online spaces is undeniable. Government representatives use social media to make official statements, consumers purchase goods online, relationships are born on dating apps, and the gap between physical reality and abstract locations has narrowed to the point that it's almost nonexistent. The things we do and say online impact physical life and vice versa.
But once you start to consider the issue a bit, it becomes more complex, as it calls into question postmodern existence itself. If the court were to decide that the ADA doesn't apply online, it would contradict rulings in other contexts acknowledging the web as an intertwined aspect of American life, part and parcel of reality, not divisible or abstracted at all.
