Go go quantum computing in 100 years.
perhaps that's true, but tunneling and heat dissipation are different in that they are physical limits that will literally not allow the device to operate, economically or not.

as for quantum computing, it unfortunately is only more efficient than a classical computer for a rather circumscribed set of a problems, if it can be implemented at all.
