But what's catching your eye right now?

That's a very good question.

One thing that has to be kept in mind when you're looking at trends is that people forget technology's plateau.

In other words, they always assume that if the curve is going up, it will go up and up and up forever doesn't you look at any technology it will go like a rocket at first and then it'll go like that because it's a plateau that's reached and you have to bear that in mind when you're looking at trends aviation the first 70 years of aviation were insane incredible jumps but nowadays you have to struggle for every new advance because so many of the fundamentals have been invented When the first rockets, real rockets, were shot by the Germans in 1942, they were already working near the theoretical limit of the technology.

And with chemical rockets, we really haven't gone that much further.

We do it mainly by reducing the weight of the rocket and simplifying it.

But the actual fundamental of the machine, we're stuck with what we've got until we do a whole new technology.

Exactly.
