We’re also, in my view, hitting the limits of what certain technologies can do. Internal combustion engines, for example, are near the limit of what they can do as far as efficiency is concerned. We’re also bumping into the limits as far as semiconductors are concerned.

There’s also diminishing returns with trying to wring out the very last piece of efficiency from a system, so yes, I do think we’re going to see a plateau in terms of technological progress, at least in some areas.
