Note that very long run GDP per capita growth is driven more or less by technological change, and there's no reason to expect that technological change is constant.
Major technological innovations are often discrete, their impact can take decades to be fully realized in the economy, and the timing of the next major innovation is unpredictable.
There is a great deal of grumbling, dour dissent with any sort of technological change outside of the tech sector - aka the "true believers". I'd stop short of calling it Luddism but it's like that.
I've presented far too many solutions to non-specialists who stared in unblinking misunderstanding at these solutions to think otherwise.
