First of all natural selection doesn't happen per se, nor is controlled by some inherent mechanism, it's the by product of many factors external and internal. So the comparison is just wrong. Human engineering is an interative process not a selection. And if we want to call it selection, even though it is a stretch, we're controlling it, we the master of puppets, natural selection is anything but a controlled process. We don't select a more resistant wing, we engineer the wing with a high bending tolerance, again it's an iterative process

We do select for a more resistant wing. How did we determine that this wing is more resistant? We modeled its bending tolerance and selected this particular design against other designs that had worse evaluated results for bending tolerance.

And that, my friend, is just engineering, like I said above it's an iterative process. There is no "natural selection" from random shaped wings

First, how did we model the bending tolerance if everything is just randomness?

Second, there are other algorithms that constructively find a solution and don't work at all like genetic algorithms, such as mathematical solvers.

Third, sometimes, a design is also simply thought up by a human, based on their own professional skills and past experience.

Yes, and it was an intentional process.

Natural selectiom:

- is not an intentional process

- does not find "the strongest the fittest the fastest etc."

By that logic, everything humans do is per definition result of natural selection. Everything is a sphere if you zoom out far enough.

However your starting definition was more limited. it was specifically about "creating candidates at random, then just picking the one that performs best" - and that's definitely not how airplanes are designed.

(It's not even how LLMs work, in fact)
