If your trip ended where it started, you just wasted energy.
Or more precisly, if your trip is a closed path, you wasted exergy.

Yes, but the Earth rotated and revolved, the Sun moved, and the galaxy moved, while I did it. Of course motion is all relative.
If I sit still relative to observer A he would say I had no motion and no kinetic energy. If observer B is moving at a constant velocity relative to A and I, then B would say I have kinetic energy.
But in both cases my kinetic energy did not change.
Yet if I fired a rocket to accelerate (in both inertial frames A and B) away from A, decelerate and stop relative to A, then turn around, and accelerate back, then decelerate and stop where I started, I would expend chemical energy relative to both frames even though my kenetic energy never changed.
If I used other energy (chemical, solar radiation, nuclear) to generate power and ran programs to train the next AI model, I may not have wasted energy. Of course that is a matter of perspective (mental).
Round and round we go!

@meikeisblonde I get that :) I was just kind of making a joke because it all depends on the point of view. If you just look at yourself from a physical point of view, if you've arrived at the same point you started, your path is a closed curve, then you really just wasted exergy since your potential energy didn't change.

@Luke73 Alright, let's say that's right, under the added conditions "when you look at yourself from a physical point of view" :) Even then I'm struggling to see what is the point you're trying to make here. :)

@JoyfulSilence I don't think so it has nothing to do with the topic dropped, you are driving things other way around
