Even on a logarithmic scale it's spiked above the trend. I would feel a lot more comfortable if it dipped again for now, or at least slowed to steady exponential growth.
Haha, we are calling exponential growth 'steady' now
To a physicist or mathematician, it can be. Its a proportionality thing.
To clarify: It would be nice to see the growth rate fit a curve with a zero gradient second derivative, i.e. steady acceleration, none of this increasing rate of change of the rate of change malarkey.
