Wasn't Einstein'srelativity a product of intuition rather than of calculation? And, intuition of processes that far exceed the bounds that Darwinian evolution

Wasn't Einstein'srelativity a product of intuition rather than of calculation? And, intuition of processes that far exceed the bounds that Darwinian evolution would have prepared us for? If we all just shut up and calculated, we'd still be doing Lorentz transforms near speed of light "just because they work", right?
