So, Heathrow........

What kind of question is that?  Air travel isn't rocketing because of business travellers.  Its booming because of lo-cost airlines and regional airports.
Unless you can show otherwise.
So what really is the point of your question?

Do you think air travel will increase or decrease? Sorry thought "Which" covered that. If business travel decreases with you thinking there will be more use of Skype, and 3D printing but increases because of holidaymakers then is that no increase? It all works out neutral. Or what?

The Americans have a lot of infrastructure to repair or rebuild, they've not even scratched the surface on that problem yet last time I checked.

The more advanced our technology, the longer it takes to get anything done

The time it will take us to build HS2, the victorians could have built, probably did build, an entire train network using the most primitive tools.
