How do you propose that evolution can occur without diversity? How can you discard the "less-fit" and retain the "more-fit" variations, if there is no variation?

They are convinced that they have the end-all-be-all solution, so there is not going to be any need to ever have anything different (either at the kernel level or at the 'low level system, i.e. systemd' level

One gene mutation or refactoring at a time.

That's not evolution, that's intelligent design :)

Right, but then you have diversity between the original allele/factoring and the new one.

If the old variation is fitter, the new one dies out/is ignored. If the new one is fitter, the old one dies out/is discarded. If they are equally fit, they both spread throughout the population.

(Note, "fitness" is a wide-ranging property. With regards to code changes, if two variants are equally performant and equally simple, then one might be "more fit" simply because it is more widely adopted, and minimising the set of patches you have to others increases the "fitness" of your tree.)

I think the misunderstanding is in the definition of "diversity". Where does it start?

Arrggghhhh!

That's not evolution, that's social-darwinistic misinterpretation of evolution.

In nature, something doesn't die out because there's an other species that's "more fit". If that were the case, we wouldn't have so many species on earth. A species dies out if it is _not fit enough_ to adapt to changing environmental circumstances (which might be the pressure of other inhabitants of that environment, but that's seldom the case).

Selection does *not* mean only the fittest survive. It means the unfit-to-adapt die.

The evolution moves to a different part of the stack.
