Among the first wave of tunneling projects under way are subway extensions, highway re-siting projects, and petrochemical repositories. These will pave the way to further standardization and automation needed for transnational, Chunnel-type digs. The East - which has never been shy about big engineering - will likely plow down first, linking Japan and Korea, China and Japan, and Taiwan and China. The West might follow by tunneling under the Gibraltar and Bering straits.
The last stop on this train is the ultimate TBM megaproject: a supersonic world subway. Maglev trains running through depressurized tunnels are the logical successor to airplanes, at least between large cities. Magnetic levitation would eliminate rolling resistance, and the vacuum does the same to air resistance. The trains could "fly" down the tracks at many times the speed of the Concorde - without creating a sonic boom. In a couple of decades, we may see a world where major international cities are within a few hours' commute of each other.
I don't know that I would enjoy living underground. But something like a mall, or a stadium could be nice to visit. And underground travel like referenced above would be an interesting alternative to flying.

90 minutes from New York to Paris...
Wow, a Steely Dan song comes true!
