All fields seems to follow something like an S curve. It starts off slowly as the foundation is laid (aerodynamic understanding, electric generator, etc etc) then then goes near vertical for a number of decades as the possibilities that said foundation unlocked gets plucked. And then it flattens out again as it starts running into physical limitations etc. Never mind that the last century or so saw two massive, highly technological, wars. Wars, to be a bit cynical, is the one thing that seems to get a free pass when it comes to the politics of money.
