We're geeks and nerds. We don't get out much. We kind of expect everything to increase at a rate similar to Moore's Law and anything less means there's a conspiracy [...].
Not specifically, it's more along the lines that, if we want to store unreliable "renewable" energy, we'll need a boatload of batteries, which is a field which has been pretty much stagnating. This really comes down to the fact that "those in power" are comfortably shoveling "progress" on actual engineer, or "some" smart ass, without looking at the math. Efficiency follows a logarithmic scale, which mean it's easy to make 90% of the gain, but the more to tend toward 100% of the physically possible, the more difficult it gets. Look at Intel, they're starting to get bitten hard because they are reaching hard physical limits... I made this prediction 20 years ago during recess in secondary, everybody laugh at me.
