I was born in a time when Velcro didn't exist. When we wanted to affix something in the way Velcro does, we had to tie knots, or deal with straps and clasps. Velcro made things so much better.
And the way it came about wasn't some genius working in a lab like Edison. It was some guy studying the way burrs stick to animal hairs and upon close inspection saw how the little hooks fasten to the hair shafts.
Now we have to remember that without the development of plastics that can easily be manufactured to create these tiny hooks in massive quantities, small but tough, the development of Velcro would have been well-nigh impossible. So it goes to show you that just knowing how a process works is not enough. You still may have to wait until you have access to superior materials to create a feasible product.
Anyway, my faith in humanity is restored every time I tie down my pant leg with a Velcro strap for another ride on the bike. Patient study of how nature does its stuff will lead us to create better outcomes with our stuff. That is if we can accept the conclusions of what nature tells us.
