You could easily turn the clock 30 years back and ask the same question with smartphones/computers.
When a truly profound device hits the market we’ll see a very creative race to come up with all the different uses for it imho.
I think you need to look at the phrase 'truly profound' that you're using and consider what that actually means in context: the world wide Web has had a truly profound impact on human development contrasted to promote media.
