But you don't know that. Maybe they would randomly get that mutation in some generation that we would then breed for. All we're doing is speeding that up with science.

Probably only on a million year time frame. We've coated a decent portion of the Earth's crust in crops. It's all being irradiated by the sun all day long, decade after decade, but the mutations people want aren't always appearing naturally. Some changes appear to be extremely unlikely.

Which is probably good, or we'd all probably get weird cases of allergies from strange plant mutations.

How exactly would an apple "randomly" acquire a jellyfish gene?

The same way that fish eventually acquired the "lungs" genes.

Which took a million years. But now watch out - we can do it in 4 hours. That's the difference.

That's not how it works. There are not one universal set of genes for "lungs". When two species develop a similar characteristic, the genes are still completely different.
